J.S.
You said, "After everything I have done for her all of these years and all things I had to put off or do without and she wants to live with him!!??!!! SIGH!!!"
Honey, this isn't about you. It's about your daughter and her father. It has nothing at all to do with you other than the fact that you raised her well enough and strong enough to be secure in her knowledge that you love her so much that she can visit her father, maybe even live with him, and you'll still love her and not have hurt feelings over it. This has nothing to do with your sacrifices and all you've done for her, and I assume with the fact that he's done nothing/very little to "deserve" a visit, let alone her love.
This is not her rejecting you. This is her wanting to get to know her father. And she might not be there for very long if he's still as wonderful as he was when he ditched her as a baby.
This is her spreading her wings, satisfying her curiosity, and attempting to get to know her father. She's attempting to establish a relationship with him, which in all honesty was HIS responsibility since he's the parent. But she's a child that wants her father's love. I'm sure she has questions for him. So let her get her answers and try not to take this all so personally.
