Oh BC, listen to PDT on this one. We ALL don't want this. Hell, I'm going to be filing for D and asking for sole custody of my kids and no maintenance for her and while her sub-conscious would be fine with that, her self-image is going to fight me tooth and nail on it. I REALLY REALLY DON'T WANT THIS TO BE HAPPENING. Your situation is worse than mine. I understand.
When I quit asking my W what she was doing and who she was doing it with, things got better. When I quit telling her what I was doing and who I was doing it with, things got better again. When I decided that my self-respect was more important than trying to keep together a marriage with someone who was treating me the way she has been treating me, things got pretty good.
Now, I don't care who she is sleeping with and where she is sleeping and if the guy in the truck next to me at the stoplight is sleeping with her. I'VE MOVED ON.
It took me a while and Sandi and PDT both had things to say to me that I'm coming back around to doing, but, I wasn't in a place to receive what they were saying back then.
You are going to have to do the same thing. You are here asking for advice and then not taking it. That's fine, but, you keep asking for more advice. The advice is the same. Let her experience the consequences of her actions and in the meantime, move on and get a life.
