Why only full therapy if you get back together? Is he just playing with it now, to entice you to think he's changed? Still sounds like it might be all about him.

You can have him in your daughter's life without remarrying now. Allow more contact and that way you'll see how much or little he's changed.

Narcissism is a very difficult disorder to heal...and if the person isn't fully invested in it, for a long time...in fact maybe working on him/herself forever... things don't change with them and how they put themselves first and best.

I know you want a family, but at what cost? Having the child find out for herself that her dad is all about "dad" wouldn't be the best either, you think?
