Summary: Guy went to jail, wife got gang banged by the guys 4-5+ guys (she's not sure, but there was at least 3 ejaculations inside her) gotta love some of the great advice there.

My personal favorite:

I just think you owe it to her and your children to try to overcome these feelings and forgive her if you can. I'm not saying it's going to be easy. I actually think counseling would be a very good idea for you at this point. I'd say talk to a therapist for a while, then see how you feel and what you want to do. Don't let your anger at the moment cloud your judgment.

Also, your friends didn't have the last laugh. They got to screw her once. You went on to marry this hot chick and have a beautiful family with her. That's getting the last laugh. Of course, if you lose all of that because of what they did in the past, then you're right, they will have had the very last laugh.
