Wiser post than mine are sure to follow. But-you know the answer yourself-don't you? I think I know what U would tell me-don't accept calls. Why bring up something to her that would make her have a heart twinge or brain fart? Abusers have their nerve wanting and even demanding things-just like a rotten child.

Hugs to you and your daughter!!!!!!!!
