Yep, me too, standard boomerang. I thought he was an "off and on", but RCR told me that he is in too regular contact for that. It's all about the children; up until about a year and a half ago it was sometimes about him as well, when things weren't going so well for him, but that stopped. We hear from him each week, pretty much just admin, as to when he's going to come see them or drive them to activities.
I still find myself having excuses for contact, even if it is just to check on arrangements (but sometimes I really do need to know...), that gets less and less all the time. I do reflect on what I have done "wrong" throughout this process, but them remember that it takes a long time for the LBS to learn as well. I have a life.
Recently he had called and seen a few old friends as well, wanting them to see his new life and accept him as he is now (as far as anyone can tell).
The worst of the replay lasted 2.5 years, the manic bit, but it's hard to tell where he is. He's on job/venture number 4, keeps updating his apartment or buying new toys (cars, etc.); has taken many short and 3 long-haul trips abroad, is on OW5 by my count, not counting just "dates".
It's weird not really knowing anything about his life; I stopped asking ages ago, and know only what he chooses to tell. I do sometimes think that yes, it would be easier if he was a totally nutty clinger, at least then I would know that he is nuts; this way he seems so sane so often that it makes you wonder.
This takes a long time.
