Ouch. I know it hurts to see her being so matter of fact about the situation. I think this would be the exact response I would get from my H.
By the way, I hate the condescending comments from WAS's when they say, of course I care about you, you are the kids' parent. Urgh!
Keep trying to think of the positive in that if you have a positive relationship for the sake of your D, then that in itself is a triump for your child. Remain hopeful that if there is more interaction with WAS, there is more opportunity for her to see what she is leaving behind. Paint yourself in a very attractive light and always be fun and upbeat when around her!
