Whats The Best Way to Deal With Meddling?

Alright well I'll try and answer this although it kinda confuses me because i don't if your best friend is a girl or guy. But what it sounds like is that H or B could be jealous and not want to see you go with someone who they think will hurt you. In some ways they are being good friends, but telling the girl that she is not good enough is just mean. I say you talk to L and tell her how you feel and that you did not tell H and B to say that.
