Your sitch is an odd one...OM telling W she should try with you? W really thinks kids will be better off with D'd parents?
Anyway, sounds like your W is very lost as you say. She certainly doesn't sound very happy, bar hopping and hanging out with an OM that she admits she'll never love. Perhaps one day she will find herself and figure out what she wants out of life. You on the other hand sound real good. Keep on keepin on.
