Your decision to make a stand. What else can you do? I think from reading your posts in the other thread, that H is feeling helpless and without direction. It was definatly your move. It sounds like he wants to get over the OW. Rest assured, she is tempting him now more than ever. He needs to realize this, and stay the course. Now, when he comes back crying, you need to be firm with him. Tell him that this A has to end now. This sounds tripe, but you have to fight to save your marriage.
This next para will probably get me black listed, or at the very least piss some women off here. but here goes..
Why was it so hard to stay away from the OW? She tempted me. I'm going to put this bluntly. Sex is a powerful drug, men are weak and certain (less scrupulous) women know how to use that. Especailly one that is desperate. recently divorced, in the proccess or otherwise on the rebound.. I'm not saying that I was the victim.. All I am saying is that I was caught up in the "fantasy-land".
