U-turn, I've always read your thread, I just never had any idea what to say. When my H was living at home and the kids didn't know, I called it limbo. But I knew H wanted out. You are living in a whole different level of limbo--she won't leave!!
The only thing I'll say is something I posted on my thread a while back. My dear friend who is a priest asked me how long I was going to live S but not D, knowing I can't truly move on without that legal status. He said, life is short. And he wasn't pushing me to do anything I wasn't ready to do, wasn't telling me to give up on my M, but pointing out that sometimes we need to let go of things to get to something better. Maybe it's time for you to force the issue with your W, u-turn. So you can have something better.
