Great advice already.
I will only add, REMEMBER the 3 C's:
You didn't CAUSE it,
You can't CONTROL it, and
You can't CURE it.
Also, check your OWN MOTIVES, do some writing, what are those motives,................hopes that this time he will change? Hope that folks will look at you as a kinder person than you already are? Hope to make yourself feel good? Trying to help him? (You can't). etc
I believe that if you are honest in your writings you will have your own answer.
