Wow, she puts her father before you? That's bazaar. As far as her putting the OM ahead of you, that is a phase and I think it will go away eventually. I think she is really messed up right now. I would definately give your support for her and tell her that you will be there for her.
It can't hurt only help. Im sorry I couldn't offer any more advice to you, but I will pray that it works. If she only knew what she was missing.
Blessings~
