Question #11: My wife of 17 years (we have been living together for 30 years) has been secretly having a lesbian affair for 6 years. She can’t choose between us, but I have told her that I can’t share her. I want out of the marriage. She insists that she doesn’t want to loose me, but she won’t make a choice! She wants her cake and pie! We own some property jointly and have jointly owned investments. What now?
