What?

Ive been with my husband for the last 10 yrs., but have only been married for almost 2! He has been there to help me raise my daughter. The problem is, is that I found out he had an affair...with my daughter! What am I supposed to do

You should call the cops. That level of incest is against the law. As far as I know only like 4th+ cusins are allowed to date leagally. Obviously sense he is having an affair he doesn't care enough to only think about you that way. Sorry.
