Dude that is one fecked up situation, I really feel for you and your daughter. I don't know what advice to offer as I've never been in a situation remotely similar. All I can do is tell you to be strong and try to think rationally. Not sure how a reconciliation will work as I'm highly doubtful that you'll ever regain your trust in her, however, given that there is a child involved, I think it's something you should give serious consideration to.
