She only wanted him back because he probably gave her stability in life.

Why ask any of these questions ? Your marriage is over . Period !

The difference between one time and a hundred is that once you can "forgive" but there is no forgiving an entire week cause the reason for the first time was kinda valid like him not condoning but still

You were a fool to stay one night in the house with her. You should have left and not seen her until AFTER the papers were served.

Part 3 please

I don't believe in best friend

Part two still didn't give any kind of conclusions...

Why did you let her go alone ??? That was dumb !
