choddeu na yaaar ke garira.  i also have so many close frens who are boys and girls.  but i dont need them in everyday of my life.  if she has bf and her bf does nt like you, it would be better if you keep distance with them.  well, i think sathi bhane pani, sometimes its attraction betweem two people.  you dont need to tell her that your bf does nt like you and this is the reason you are keeping distance with her.  if you guys are living in same area, then i can not say, but if you are not living in same area, try to keep distance with her.  your contact with her will definitely slow down this way and you dont need to worry much after that.  she will be happy with her bf if she really like him so much.
