Not everyone that has met a Twin Flame is willing to change their life situation to pursue a union.
The changes that we Twin Flames go through are accelerated, unexpected, and not in our power to control the nature of the process of change.
A Twin Flame would therefore choose to run into marriage with someone else because it feels easier and safe.
Fearing the changes & uncertainty
When you meet a Twin Flame, it is not always roses and peaches.
You go through excruciating chaotic emotions.
Your dreams change.
Your emotional well-being is destabilized.
You go through a series of energetic cleansing.
You are forced to make a change to align yourself with the new Twin Flame shared energy.
