Re: he
Very interesting read. Personally, I believe that when there are issues in our relationship with someone, we should reflect deeply into our own behavior first.
From your narration, I have felt that you are very defensive. If you commit a mistake, I think you try to defend your actions instead of accepting your fault. This can be all unintentional and not premeditated. This friend of your seems to be fed up with this attitude and he wants you to accept your mistakes and not pretend to be Mr. All Right.
