Ok im may be totally wrong here, but I'm not sure you can really do much about the OM anyways. But imho your just driving her closer to him, im sure he's showing her the texts, and their saying "See, he is crazy"

Now what do you think would happen if you backed totally out of the sitch. Let him play his little games, and she finally notices he's the one playing games. Affairs usually play out pretty fast if you let them see that the relationship is built on lies, confusion, and acting out.

Right now, as the third wheel, your making it easy for her. Shut your FB acct down for a couple of weeks. You have no control over the situation, and I think if you can give yourself, and them some time, it will come crashing down all by itself. This guy really doesn't want to raise your kids. He's just playing the game right now, cause your driving her right into his arms. Its easy to play the game when your giving him all the winning cards, u know?

On top of it all, your mind reading, trying to control a situation you cant, jealous and none of those are traits that your wife finds attractive. MWD says that if your doing something that's not working, try something else, guess what, its time. It doesn't matter what you think, its what your wife is thinking. Your not being the spouse your wife would be crazy to leave, your the spouse your wife is crazy to stay with.

I hope im not being too forward or rude. That's not my intention. Just trying to give you an outside, neutral prospective. What are you doing to 180? What are you doing to GAL and detach?
