Did he say or do anything while talking to this "other woman"? Maybe he opened up about things bc anonymity makes that much easier and these are things he wouldn't have said to you and now he is embarrassed? If that is the case, I would understand his embarrassment. But on the other hand....I'd be worried that he has all these things he couldn't open up about to his own wife!

I'm not sure how I would feel if I had broken up with my bf and he did that...I'd probably be pretty peeved too. And maybe he really DID think he was over it but isn't? That I have done before. Said it was okay, and really truly felt that it was - then over the next weeks realized that it really still did bother me.

Either way you need to have an open talk with him. But, keep in mind, if he isn't ready and you keep pushing - it will only make the situation worse and you will push him away even more. He gave you your time to be honest, you have to do the same with him. Hope everything turns out okay...
