It's okay Kerry. Let her have her own pity party and feel like the victim. It probably won't last and I think you'll end up ahead in the long run. She just needs a little time to process. The things you asked weren't unreasonable and they weren't vindictive...just reality. Maybe she'll eventually face that reality. She really is living in la la land. Basically I think she wanted it all...OM's house and car and pretty much free access to you whenever she needed what you have to offer. Give it a little time and see what happens...all the while maintaining your friendly attitude.
Good luck.
