OL, I'm talking to myself here as much as too you. My W and I have been getting along well recently. It hurts like hell. I want more. I want to fix the problems we had/have and go on to a great life together. She, last I heard, still doesn't know if she wants to be with me or not.
I do have a point here. I need to go back to the basics; detach, GAL, and give her space. I think you do too. You say the vacant look was gone for a bit, and that there was a positive reaction (maybe you should explain more about that). But, I hate to point it out, she called the OM while she was with you. I assume she still expects you out of the house in about 20 days. OL, Don't talk to her about the OM, don't bring up your R. You aren't her best friend right now. She may be trying to be 'nice' to you as she see's it, but it doesn't mean she is softening toward you or will suddenly realize you're the one she wants to be with.
I understand your desire to leave on a positive note, and maintain a friendship of somekind. You don't have to be nasty to her. But it's dangerous to talk about OM, the M, even the future.
I see it working for me. When I pull back, give her space, she comes toward me. If I reach out, she pulls back.
I almost hate it most when she gives me a hug. It can hurt, right? Thinking about that hug for the next few days, wondering if it means anything, wondering if it's a sign of hope for the R.
It is stange, ain't it. They are, and I guess we are too.
