Okay, now that I have a little more time, here are some of the things her parents can do to her if they don't like her behavior or who she is seeing, all of which are completely legal and for which she will have no recourse:
They can take the door of her bedroom off its hinges, remove everything from her room and leave her with a mattress on the floor and two changes of weather-appropriate clothing of their choice. They can lock and/or alarm all the doors and windows so that she cannot leave the house without their knowledge. They can confiscate all her books, games, electronics and other possessions; if she needs a computer for school they can require that she use it in the living room under their supervision. They can put a keystroker on the machine so that they can see what she is doing on it. They can ground her from now until her 18th birthday, allowing her out of the house only for school and religious services, if religious services are a part of their family. They can escort her to and from school and if they so choose, even attend classes with her. If she has a job, they can force her to quit it. If she belongs to any clubs or meetings, they can force her to quit them as well. They can essentially sentence her to two years of sitting in a chair with her hands folded, wearing clothing that they pick out for her, doing nothing other than school, and the law will look the other way because it will all be completely legal.
This is exactly what her father has done to her but it just gets worse. That's honestly an accurate description of what her home life is.
Anyways, just got off the phone with General Sessions, Juvenile, and the probation office to look up to see if there is anything on mine, her, her fathers, and even my parents in case he filed it against them. None of them couldn't find anything, Juvenile said anything regarding Juvenile records are classified. They said I probably don't have one out against me however it's most likely apart of the probation. This gives me reassurance and takes some weight off me because I was worried this would show up on my record and could possibly refrain me from going a certain career. The best thing for me to do is even after her probation is over, I'll refrain contact to avoid her father actually getting an order of protection/restraining order. One of the Clerks told me it wouldn't have even been possible for her father to get one against me because it's only for divorces, family, not exactly suited for my situation. Not sure, it's just what they told me. Perhaps when she is 18 and is a legal adult we could try dating again, at the very least then her father won't have jurisdiction over her. I understand this all sounds like a naive 17-year-old boy who got himself into this mess and sounds like I'm trying to get involved more and more but I'm just looking for clarification and peace for myself to avoid any future mistakes and to prevent it happening again. Thanks for all help and criticism, I will try to not take it for granted and will refrain from making this situation worse.
