I still think he's on a fishing expedition and is hoping that he can prove that you have a closet full of money. You aren't remarried and like you said, the relationship could go sour and then what? I definitely would fight this one. He's apparently very jealous and vindictive enough to pull this stunt because he doesn't want to pay spousal support and he probably doesn't like it that you are living better than he is.
I do hope that everything works out for you. I knew your xh was going to be a PITA because he just can't let go and he needs to have drama floating around all of the time. Stand your ground.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
