Same thing with me, didn't do anything wrong. Now, I don't mind if he accuses me of doing something really terrible (I did not hit her, I DID NOT! Oh, hi Mark.) just want to stop fighting. Now when I try to explain that to him...well actually since he won't talk to me I really can't explain that to him so that's the problem. Bottom line: No more fights.
well not sure but it sounds as if this is a dispute about something that happened with a third person, if you can patch/resolve what happened with the the third person in stead of your friend that might work, other wise, if your friend does not want to talk there is no way to force them to listen and patch things up at the same time.
and never, never, never bring up blame, if it does come up just accept it if its toward you even if its not your fault, which is more important, the friend or pride? usually its the friend.
