Point well taken. I don't know if I'd thought about in only that context. I've primarily been thinking about her as a 'package' deal.
You are absolutley correct though. The first question does need to be 'Can I live with her?'. If the answer is no...then everything else is a moot point. If the answer is yes (or maybe) then the baby enters the picture.
Thanks for your insight!
BTW - spoke to her again tonight, as we do basically every day since the kids are with me almost all of the time. She was at OM's house and has been all weekend. Seems she isn't done with him after all. At least it makes my decision making a littel easier
