You also need to take into account the man who raised her. The man who she knows as Daddy.
How does he feel about all this.
I think maybe the daughter will be hurt for a while , but the one who raised her will always be Daddy.
I don't mean to hurt you , but don't expect her to throw her arms around you and say she's happy. She's had one Daddy and that's the man who is really Daddy.
