You've just got to have a sense of respect for the person you have children with. Anger doesn't help anybody. Ultimately you have to say forgiveness is important and honoring what you had together is important. But it's easy to say and harder to do.
I don't know what religious people do. I kind of wished I'd been a Christian with the blind faith that God is doing the right thing. As a Buddhist you feel like you have more control over the situation and that you can change your karma.
