Thanks all. While I know I'm not intentionally being mean to deny her access to being in this house overnight, it does make me feel pretty rotten. Maternal instincts (I have two of my own) just don't support locking a child of any age out of your home. Even if it's not your child. I'll fully admit that I don't like this young woman very much, but I do care deeply for her. Does that even make sense? And who knows.....maybe I will learn that she is likeable if she will ever get treatment for this. Maybe I've never seen what's really inside of her? I want so much for her to get better - for her sake and for this family's sake. I've tried to take the approach with my husband that, if she was my daughter, I'd much rather learn that her behavior is caused by a disorder that can be treated and managed (and her life improved) than to think she is just being evil for the sake of being evil.

Thanks again.
