Hey Neighbor! I think boundaries are the biggest problem for me right now. We've been separated for a month but somehow I see her on a daily basis. Tuesday she even 'showed up' out in front of my youngest daughter's school when she knew I would be picking her up. She didn't have anything to drop off, I think she just wanted to see the kids a few hours before I was scheduled to drop them off.
I didn't get too nasty with her, just spelled it out in no uncertain terms.
