When my daughter was in her teen years she dated a boy that I knew was abusive. So I bought a copy of the book, Beauty and the Beast, and I would read it a lot. One of the things that I believe was in that book was about giving the obsessive person hope of a relationship. It said that if a person calls you 11 times and you do not answer the first ten, but then you pick up on the 11th time, that is telling him that he can still get to you. That has stuck with me because it applies to all situations in life where you want to enforce a boundary. It says to me, like Laurie said, NO means NO. My daughter is still in a similar situation with her boyfriend so I really do feel for you. Hugs, Marle
