The only way you can earn trust with your parents is to prove to them you can be trusted. If they see you interact with him over a period of time in a way that is not flirty, they would feel better about letting the two of you hang out in your room. I think its not such a big deal to watch a movie in the family room, and if you want to talk privately, go on a walk or something. I wouldn't let my daughter be in her room alone with a boy, even if the door is open.
