Aha! So Puppy doesn't tell his wife about speeding tickets. I'm just saying that I think requiring complete and total honesty in a marriage is not realistic.
I am not here to judge whether Didi should tell him or not. I think it is up to her. I agree with her that he already knows about this affair. He hopes it is gone. But he must know their relationship is not all it should be at this point. He should be worried about her slipping back into it.
My point is that she is comparing a sexual relationship with OM to a non-sexual relationship with H, and the one with H doesn't compare well. Gee, what a surprise! I think if she built the relationship with H up into a sexual relationship she would be on the road to fixing this mess.
