Yeah, what Sybs said.

I don't mean this in a nasty way Qoji, but you don't seem to grasp the importance of a union cemented by children.
The only times you can just cut and leave wihtout trying are when the solid lines of repeated physical abuse, etc, are crossed. Serious things.

It would set an awful example to a child if their parents didn't explore every avenue of reconcilliation and problem solving before ending a relationship. Even if you fall out of love with someone, it can be worth trying to make things new again, getting counselling, before breaking up a home.
