You've been divorced for over 1-1/2 years and even after that much time she won't have lunch with you even though you're in the same building. And she won't go to your show even though it would be completely benign if she did. As much as I admire your tenacity in trying to reconcile, it may be time for you to consider dropping the rope. I'm not saying there will never be a chance for reconciliation because I've read stories where people have been divorced for years and then against all odds got back together. But I am saying that your X is clearly indicating to you that she has zero interest in you right now. So moving on may be the healthiest thing for you to do.
