IMO you guys are moving back into things too fast. She hasn't even told you whether OM is out of the picture and she still hangs out with his mom? I would not be comfortable with that situation at all. Spending time with your spouse with all of those questions looming in the background is putting yourself in a REALLY difficult situation. Especially going out of town together because now you don't really have a way to escape and take a time out for yourself if things get bad.
I don't know that I have advice, I just don't think I would have put myself in this situation in the first place until my spouse was showing me that they absolutely were ready to reconcile and start working on the M. You stated earlier that you didn't even know if you were wanting to work on the M. What did you mean by that? You seem like you really want her in your life? What is it that you really want?
