David and I are very different individuals with respect to our personalities, character traits, values, and behavior.  I will never be like David and he will never be like me.  However, despite our vast differences, I love David, as he is my brother, and I have no reason to doubt that he loves me.  When he wishes to talk to me, he calls and when I wish to talk to him, I call.  I have seen him when I am in New York City and he has visited me when he is in Washington, D.C.

I am not sure what "reconcile" and "heal" mean to you.  If they mean that I adopt David's views, values, and traits and start acting like him, that won't happen just as David will never adopt my views, values, and traits and act like me.
