Fi don't forget DD has been out on her own for a fair while now. Paying her own way, getting home in time for curfew (which apparently can't happen for your parents) cooking every second night and cleaning too. She nearly failed exams because she didn't show up claiming how hard done by she was. She ranted about all that crap and it fell on deaf ears.
She asked for independence and got it. It was really hard for me - but sort of not, the attitude was vomit inducing but I really, truly let her go. She learnt.

I don't think you should help her financially if she moves out. Otherwise yes, not for the $$$. I think sense of entitlement with go through the roof...
