My ex man left his wife for me and we went out for seven months. But once reality hit and he had deal with custody battles and lawyer fees he got a little depressed. I got impatient and went and told his wife we were through. He forgave me but when his kids got mad at him he broke it off. I can't tell you how many times I've said sorry but he said its over and he has to focus on his custody battle.

He loved me so much and left his family for me. My question is, will he ever forgive me? I didn't break his marriage up he wanted out years before he met me

You dipped in his business with his kids, you went to his wife. He may have wanted out and you were a way out. Like you said once reality hit he realized he made a mistake.
He may not come back to you. Seven months is not a long time to throw away a family over.

He probably found a better female, one that wouldn't mess up his reality, through impatience after just 7 months of dating. He may be back for a booty call later.
