You have talked a lot about the person whom you called one of your friends. You are complaining about her attitude. You know you need two hands to clap. If you are being irritated by a person you'd better avoid as much as you can. This is the Sunnah of our beloved prophet Muhammad (P.B.U.H) to forgive what others misbehave. But remember you should not involve in any misconduct otherwise there will not be any difference between her and you.
