Don't know enough about MLC to make any kind of intelligent statement, but whatever you call it she is in a phase where she needs to discover herself. I think that regardless of what you call it, divorced women seem to at least display some of these features. The urge to rediscover lost youth, act younger, dress younger, get tattoos or new piercings, at least superficially change values that at one point seemed ingrained, critical of themselves and others, dissatisfaction with life, openly expressing an urge for independence. Unfortunately reality at some point has to set in. A person cannot maintain this outlook indefinitely. The pendulum has to swing back.
I don't know if we'll still be waiting when the pendulum does swing. My wife has some of that. I've tried to fit in to this new attitude, although I don't know if I/we really should. Basically I guess I've been accepting that she seems a little weird right now.
You've said time and again that this has to run its rather protracted course. If you get the chance I would suggest being very accepting of the new her. It might take some of the fun out of it for her.
P.S. I hate weekends in general if I don't have my kids. I'm lonely. I miss my wife. I should e-mail you a song. But maybe I'll just post the lyrics on my thread.
