Thanks to those who have posted. Like so many others, I would not be in the place I am now in without this forum, which has offered much support and advice.
I think the MLCer realises they have lost power over us, and it scares them. My xh is now the one pushing to stay in contact.
I agree with Cadet that it feels a bit like a script playing out, and also with Snodderly that he will not sort himself out until he focuses on himself and his issues.
I do get the sense (although he cannot admit it) that he is beginning to realise what he has lost.
And my goodness the time thing - he clearly has NO CONCEPT of how much time has passed. He is talking about co-parenting adult children, not teenagers and emrging adults.
Finally I have to tell you all that I looked terrific!!! And years younger than him. Petty but satisfying.
