Casa, the original split happened in 1997. She is now 18 and already planning her life on her own, maybe even before graduating. Dad tried, but was not her bio father, so he lost that custody battle. I do not think she ever had any counseling, but would think it could've helped her, but how is that my boyfriends fault? He is considered a legal stranger to her. Yes, he was there when all this started and would have loved for things to go differently for her and cares very much for her. His only legal obligation is to the son. Considering she tells her brother such things as she hates him and wishes he would die, I don't really think she'll be too harmed if dad gains custody. The dad on many occassions has called to speak with the mother about the way the son is treated by his sister, she is often very verbal and physical with him, I have witnessed this first hand. When the mother blows it off, the dad will call the girl herself, she is old enough to know what she is doing, and the incidents seem to stop for a while. Besides, at the rate this is going, she'll probably be married with children of her own by then. I'm certain if I would be posting questions about how dad wants to obtain custody of this girl I would be getting bombarded with responses like, she has a mother, she has a father, he is not bio dad-they never married, he is a legal stranger, why does he want to take the girl from her mother, and so on. Instead, you're bashing him for not being "her father and taking away her brother" when they seperated 8 years ago. Yes, dad has concerns for the girl, but can do nothing about it. He can only change things with their son.
