Me nad my best friend bicker like couples. why am i always the one to apologize 1st?

If you fight constantly about every little thing then maybe you should just only see him once a week. Its not good to loose friends but keeping the ones that annoy the hell out of you is just as bad. Try to see him at least once every two weeks and see if you could start a conversation without any arguments. Also it would be helpful if we knew what you argued about for example interest or stuff like that.
