Only those who have multiple affairs or options.

Breakup hurts most to the person who fell in love first and deeper.Further people with no back ups or extra options are often trapped in circular vicious cycles of thinking traps. It goes in loops and their mind stops to function well. They find it extremely difficult to forget people whom they loved once.

The real problem starts when this vicious circle of thoughts is triggered. Its very difficult to stop it.

In any case the person who was genuine moves on fast and in range of three days to three months one moves on. We move on exponentially. Each day it gets twice better. But those stuck in thought circle find it extremely difficult and they get into the well at twice the speed.

If the guilty is caught in this cycle , they can never move on.
