You kind of have to look at Ot from his side. He was lied to for 9 years. And even though he may love her more than anything and should absolutely not be taking it out on her by not having anything to do with her, he may just need time to think or whatever. Of course she is still his daughter, always will be, but right now he's just hurt. I'd give him time. Although if he doesn't come around eventually or for too long of a time, then he's just completely done and at that point there's nothing you can do for that little girl. Just hope he needs time to sort things out.
