She'll probably get the job. You are all correct though, she is just not right in the head. Once again, she is trying to use the kids to have her cake and eat it too. She knows I'd love to go to Disneyworld with the kids, and she knows it's just not fun to go with only the kids, for her or me. OM is so far away, plus she knows she can't introduce OM to the kids without absolutely destroying her and my fragile R, and cranking up our estrangement to a level she probably doesn't want to deal with. OM is her private and personal little fantasy land.
No way can I go to Disneyworld with her if OM is still in the picture, and I know he is. In fact, I think I have to start enforcing more boundaries in general. I hate that my son has his young emotions invested in the state of our broken M. She can't just divide herself into two halves and give me one, and OM the other. It's not right!
I won't try to have a serious talk, as I agree with you all, she's in no state to have such a talk. I'll just decline the Disneyworld offer. Sad thing is, I'd LOVE to go :-(
