Sorry Guys I neet to Vent my Girlfriend Problems

I have a 17 yo daughter whos a straight a student and I cut her a lot of slack to spend time with her boyfriend. I see it as this. She has her priorities straight and is preparing herself for a good future.Until she acts immature or quits taking care of buisness I have to let her lead her own life. Otherwise she will resent me. I dont want that.This doesnt mean I will let anyone screw her over though.You say you see this girl once a week for the last 3 months. Do you know her history with her parents. Maybe she hasnt proven herself to them. You will have to learn to look at things objectively. If you dont you will have a snowballs chance in hell of this working because as you said the parents can make it hard on you.
