I think that the best thing to do is ask your friend why her parents are acting this way towards you. Explain to her that you think that you have been a good influence on her and that you do not understand her parents opinion of you. If she tells you why, talk to her parents about it. Explain the same thing to them. If they still have issues then I don't really know what to do about it. If you are telling the truth then you sound like a nice person, and their reasons for disliking you are unjustified.

P.S. I get people mad at me for acting like I'm right all the time too. I think we all do it. Lol.
