I can relate with the ease of detaching and looking forward to a single life. When our WAS's have the kids spending time with OP, you realize that the rope must be dropped (and possibly burned).

A 6 month boy needs to spend a lot more time with a mother. Your H is crazy to think that he is going to get what he is after. He is just going to burn a whole in his wallet in legal fees.

I read that you were thinking of calling OW so as to set your mind at ease. I called OM and I came away feeling he was a good guy to be around my kids. I did not talk about his R with my W. You probably want to avoid that issue if you do call her. I dont think I can meet OM face to face yet as the temptation for a jab, straight right, left hook, lights out would be too easy. You too might just want to stick with a phone call.

My W has been living with an older OP (31 years her senior) and is now at the point where she wants to move out. Give it time, your H may break the heart of the OW soon too.
