Thanks Trumpet. Throughout this whole process, I haven't blown up on her at all. There won't be any bull and china shop here. That's the biggest reason I stayed away from W this weekend.
If I bring it up, she will want to know how I found out. I'm sure she will deny it otherwise. I have asked her before and it was always denied. Asking her and telling her I know are very different. Intuition tells me that if I confront her, she will blow up because I snooped. I probably shouldn't care about her reaction at this point.
Good point about strength. I am strong enough to separate and work on me. I know a D wouldn't kill me, but I keep thinking two things. Did I do everything that I could possibly do to save my marriage? The answer is no. Not yet.
If it ends, I need to be able to know that the answer was yes to that question.
The next question is how? I know about GAL and DBing in general, but it's the tough love to a WW that I have a problem with. I need to take the chance to show her a loss or two without backing down from it.
Like I said, there aren't many W on here as cold as she is so its hard to predict anything from prior experience.
One other thing I want to throw out there. In the last few weeks, W began sleeping on the couch more often. Now it's 5 nights in a row. Since the MBR is now mine alone, I did a little redecorating. Added some pictures of my kids and family to the room. While out yesterday, W moved all of my pictures and placed pictures of her and her family in front of them. There is now an almost poster sized picture of W right in front of my bed. I want to move it but I also want to keep the peace.
I know. Keeping the peace is probably my biggest DB issue.
If she wants out of the room, and the M for that matter, why place a giant life size picture of her face in front of me?
