Let it go Andyv and don't read to much into it. In the early stages of our separation, my stbx had a noticeable glow on her face because of OM. The same glow she had when we were dating and first married.
18 months later, it's a different story. She's gained weight, she's often cranky, irritable, and seems to be back in the slump she was in when I moved out. I don't think it's because she thinks she made a mistake leaving me, but I think her expectations of OM are not panning out as she thought. She's still in contact with him, but I think she is starting to realize he isn't the cure all to her unhappiness. Don't know about your W, but mine really does have some internal conflicts to work out that OM isn't going to be able to fix.
Ironically, the burden for her happiness is now with the OM and when he can't deliver, she's going to wonder about allot of things she's said and done to me. Believe it or not, it's kind of liberating for me that I'm no longer responsible for her unhappiness.
I wouldn't get to bummed out about her good mood with OM. If things don't work out, you still want her to be in a good frame of mind for your kids sake. That goes for you to!
