It is very easy to assume that the runner Twin Flame finds happiness after they run from their Twin Flame especially if they find a new romantic relationship. That is not the case no matter how happy they seem with a karmic partner. The further you run from a Twin Flame, the more pain, agony, and frustration you experience because running from a Twin Flame feels like you are denying an aspect of yourself.
The inner resistance that the runner Twin Flame puts up to block feelings of unconditional love towards their divine partner consumes so much of their energy and time that it frustrates the runner all the time. When you run from a Twin Flame, you know that you are ignoring the unconditional love that you feel, and on top of this, you are constantly haunted by memories of your first encounter with your Twin Flame partner.
Suppressing the feelings of unconditional love that the runner feels makes it impossible to forget a Twin Flame because you are always haunted by my thoughts of them daily. The Twin Flame experience is a journey of accepting unconditional love and once the fear of feeling love dissolves the runner starts to heal.
Healing begins when you fully open your heart to embrace the intimidating feeling of unconditional love that your Twin Flame triggers within you. It is a once-in-a-lifetime opportunity to find a Twin Flame. Once you know how amazing they make you feel, you want to feel unconditional love forever.
There are tremendous lessons that I have learned on this Twin Flame journey. I hope that my perspective helps you.
