re: Updated** 11/29 8:38am. Cheating and forgiveness

I would require that she agree to marital counseling. Clearly if she's doing something like this, something is wrong.

And with all due respect, your nephew is only telling you his side of the story. You don't know what he may not be telling you (did he have an affair and she found out, so she ran off in return?)

If she's not willing to seek counseling, then he's likely setting himself up for failure. And if she does it again, he should dump her for good.
