This is the link to where i found it: Characteristics of Twin Flame connections

A man and a woman, who are twinflames hardly need to speak the words "I love you", knowing as surely as they do that they must belong to each other whether in this present incarnation (lifetime) or (due to karmic complication) at the end of many more centuries...The words in the marriage cermony "those which God hath joined together, let no man asunder" refer to such as these...Yet this warning is unnecessary, simply symbolic ritual, for no man can break the tie between Twinflames, not even themselves...Nor can any energy in the Universe...The Force that created them is all-powerful and indestructible...The bond may be weakened, their final union and consummation delayed, but they cannot be separated permanently...There can be no end to the kind of happiness they may claim...when they wish to do so...on a timetable dictated by the Free Will choice of the Higher Angels of their own selves...
This kind of instant magnetic attraction is often called "love at first sight" which is no accident of fate, but very real...It's more than curious coincidence that Twinflames, out of the whole huge world, should be drawn together at the appointed time...The crossing of their paths has been predistined on a Higher Level of Awareness...Certain spiritual energies are at work to bring about their meetings, as surely as the migration of birds and the return of comets are governed by a similar Universal Law...Their coming together is controlled by the workings of Karma, which is but the sum total of Causes set into motion in the Past--and these determine infallibly the conditions of the Present...when the time comes for Twinflames to incarnate, they are sent to Earth, clothed in flesh (the bodies being the Temples of the soul) through particular Time-Energy Forces, at the moment in Earth Time when certain planetary configuarations create the proper conditions...These Time-Energy Forces are electromagnetic in nature, yet more complex than this...
During the periods of twinflames being apart, however brief or however extended, both persons are lonely, empty, and incomplete...yet even throughout any such temporary spaces in their togetherness, there's a constant, pulsing astral communication between them--for even then, they are linked by a cord that connects them over the miles...
The twin soul begin to realize that their individual paths are purposely bringing them together and putting them in the same place at the same time for a reason. Twin souls tend to meet when both are at the stage to accelerate their learning and growth.
The synchronicities also occur to help show them that although they live different lives, they are also part of the same path. The mirror between the two causes them to feel a close bond with one another, and this also acts as a catalyst to personal growth and understanding of the soul. The mirroring and the synchronicity sparks wonder and curiosity to discover what is underneath the surface, and eventually they learn to look inward to find the answers and meaning to their connection. Once the twin souls take notice of this phenomena they start their mutual journey of self discovery.
Twin soul mates may sometimes share similar backgrounds to each other, and similar life experiences or events that occurred around the same time period. This is because the individual souls are working on similar issues to overcome or complementary lessons. When the individual looks inward to find wholeness, extend of 'outside of one's self' in order to feel complete, then the synchronicties will happen more often and become more meaningful.
The twin souls have lessons to learn from each other and synchronicity can be their guide. The synchronicities help to wake them up to take notice. When one is ready for awakening, so the other will be also, but it often comes down to the free will of each individual whether they are ready to look inward and take action for personal growth, or rather they will remain in the ego or shadow self.
Characteristics of Stage 1:
Both Twins recognize one another at the soul level and feel as if they have met before. synchronous events surround the union. The heart chakras open and both souls quickly merge into a third unified energy. Both Twins experience an acceleration of spiritual understanding.
The purpose of the Recognition and Temporary Spiritual Awakening Stage:
To activate the memory of each soul’s life mission and to help awaken each Twin to higher levels of consciousness.
Characteristics of Stage 2:
The initial temporary spiritual awakening (illumination) fades. The ego (“little self”) begins to re-emerge. One or both Twins may attempt to fit the relationship into the “old model” of Love, couplehood and relationship as it relates to their ego desires and learned belief
Characteristics of Stage 3:
The crisis of the Twin is realizing they must reject their egoic beliefs about Love relationships or reject their beloved. Having to shed “little self” or identity-based beliefs and desires to embrace a higher expression of Love can lead to stubbornness and anxiety. Fear can take hold, triggering many dysfunctional emotional patterns. In staying present with the patterns, they can be witnessed and released.
Despite fears, both Twins naturally come together in cycles for bonding, confession, forgiveness and Lovemaking. These rituals cement higher levels of consciousness into the energy fields of both Twins.
The purpose of the Crisis stage:
To provide opportunities for the healing and maturing of the mental and emotional bodies.system. Inner conflict arises. Twins ruminate on what they were taught to believe their beloved “should be” and how relationships are supposed to serve them.
Both Twins feel simultaneously inspired and toppled by the power of the union.
Doubts creep in making one or both Twins begin to view their beloved critically or suspiciously.
The purpose of the Testing stage:
To cause outdated mental concepts about relationships to rise to the surface to be cleared.
Characteristics of Stage 4:
The human ego naturally fears annihilation in the face of the Unified Consciousness encoded inside the Twin Flame Union. The pain body rises up and old ego survival mechanisms or “bottom of the barrel” emotional and mental patterns like defiance, resistance, manipulation, anger, punishing and judgment arise.
One or both Twins become emotionally and mentally flooded with deep pain from what feels like soul-level rejection and abandonment. The unbearable soul-level pain leads one or both Twins to withdraw physically and block communication in fear and futility. One or both Twins may unsuccessfully try to re-create the original unified harmony.
The purpose of the Runner Dynamic:
To propel both individuals towards God for healing and maturation of the spiritual body.
NOTE: The temptation to engage in ego battle or withdrawal is very seductive and difficult for many to resist, which is why many Twins never reach Surrender, Radiance or Harmony.
Remember, there is no room for judgment in Twin Soul pairings. Each soul learns from much walking its own path and choosing through its own will. Your non-attached loving thoughts will be felt by your beloved in the subconscious, keeping them strong.
Characteristics of Stage 5:
The direction and outcome of the relationship is surrendered to God in full faith and trust that the Union is under Divine Protection. It is accepted that what is best and destined for the final physical harmonizing will transpire in its own time. (Both Twins must reach Illumination in order to harmonize in the physical)
The “Runner” Twin is allowed the space and freedom to choose to evolve at their own pace in their own way. At this stage, the frequency of compassion returns and maintains itself. The Surrendered Twin holds a heart space for their beloved while fully exploring life on the way to becoming an Illuminated human. This may be a time of channeling Unconditional Love into art, music, writing, teaching, active service or some other creative outlet.
Purpose of the Surrender stage:
To help each soul release the ego, develop regular communication with God and demonstrate their full trust in God to do what is best and when.
Characteristics of Stage 6:
By this stage both Twins have awakened. They come together in the physical to assimilate their newly evolved energies, flowing into the new dynamic of their Unified Potential. Both Twins integrate fully into the third energy of Unconditional Love in a way that influences others towards their own heart opening.
Purpose of the Harmonizing stage:
To fulfill the intended mission of the Twin Flame Union.
Twin Flame relationships come into your life to help mold you to embody the vibration of Unconditional Love.
How to find the twin soul?
By knowing that the meeting is inevitable.
By being patient, waiting for the right relationship, and taking time to test the relationship at hand.
By devoting the self to increasing self-reliance while at the same time being open to relationship.
By developing tolerance: a) of one’s own failings and love-strivings, fears and depressions, in order to transmute them into something higher; and b) tolerance for others in a context of patiently relating, trying to help the other to become better through relationship.
By listening to that high mind, so close to the soul, which is called the intuition.
By blending intuition with common-sense knowledge, patience and the opportunity to experience in life whether the relationship is truly pre-destined or simply the product of one’s love-longing.
It takes a lot of honesty and healing to be able to "work" with ones twin soul. I have often seen how some people who have bonded with their twin souls become so focused on helping others so they don't consider the actual situation they are in themselves. We cannot heal other people or help other people heal, if we haven't healed our own souls. Healing doesn't mean that we are meant to be perfect, but we are meant to work through our issues and maybe see our lives in a different and a more real perspective. It is because we can see a more "whole" "view" of our own lives that we can guide people a little bit or offer some kind of help by just listening, but each and every soul has to walk his/her own path him/herself that is completely unique for that specific soul.
You must face your life, yourself here and now. You must be a soul fully alive in your physical body. You might not be able to control the overall process that has to do with your twin soul, but you can control yourself. When you feel that there has been a loss, not of just the loss of your twin soul, but also the individual loss of yourself, you will feel feelings that are not spiritual at all. It can be intense feelings of anger, hurt, unconditional love for the twin, and pain of separation. I think it is very important that you feel these feelings in you so that all your energies can flow freely through your physical body and soul. You cannot get to your twin soul during time of separation if you do not feel how deeply you at times have felt the loss of your own Self and the loss of your twin soul. The only way to the twin is therefore through your Self. You must feel all feelings to be grounded, otherwise you will never really be present here in your physical life. We have chosen to be in our physical existence to feel. When you face your self you will at the same time feel the pull from the identical energies of your twin soul. You will feel that you can only get back to your twin soul, when you are being your true and honest Self and face all the deepest feelings and wounds within yourself. Twin souls couples never completely face the same issues, yet it seems that all people who bond with their twins sooner or later must face themselves individually.
I believe that the hardest mission any sets of twin souls can face on earth, is the misson of facing the Self. With the merging and union with the twin soul, you get to feel your Self again, you become conscious again and you start asking yourself questions and you also feel that there are things in life that you don't want to put yourself up with anymore. You cannot anymore just watch your life from the outside , you need to take part in it. Some people will claim that when it comes to the twin soul process, it all happens spiritually beyond ones own control, the truth is that the twin soul process is really such a deeply personal process, so that it forces you to be 100% present in your own life. You must face your life, yourself here and now. You must be a soul fully alive in your physical body. You might not be able to control the overall process that has to do with your twin soul, but you can control yourself.
Many people who have been united with their twins and experience some sort of separation whether it is an actual physical separation or an emotional one, will very often feel that if only they could be with their twin souls in some kind of relationship, the deed would be done. This is also the reason why many female halves try to take control directly when it comes to their male halves. In desperation many female halves try to reach out for their male halves in one way or the other. Often the female halves therefore try to control the whole thing by actively trying to make the male halves move towards them. Often the female twin souls long for an emotional ”feedback” from their male halves and for this reason female twin souls tend to take emotional lead when it comes to their male counterparts. All this is done out of desperation for the other half. In reality at the level of Self, this will never work out. The reason for this is that each of the halves is forced to face their individual selves and the female halves are ”forced” to not to actively reach out for their male halves, but to reach inwards for their inner Selves.
