Dear Hardly,
It sounds like you're living a bad Sidney Sheldon novel. What you should do depends on where you want to go morally and spiritually. Right now you're sort of a high class hooker. If you're happy with that, then get the pussy job done. Just remember, your husband will never stop until you're either disfigured beyond recognition or dead.
If I were you I'd get a good divorce lawyer, find a spiritual counselor, discover who I really was, and then try to find someone who would love me for who I was, not what I was wearing or driving. Remember looks always vanish, what's inside never does. Capisce!
