When Will People Get That I don't Like His Best friend?

This is kind of like my situtation. My best friend has been dating a guy for 11 months and him and I have known him for years. Him and I always talk, his parents love me, I babysit his siblings. Everyone always thinks he is cheating on her with me but she knows I would never do that and I would never do that to her. Just ignore what everyone says and let them think what they want. :) You, Nick and Greg know the truth and that is all that matters.
