Hello Bill,   Jerry is right on the money: it could be any number of things or unresolved issues impacting his behavior.  Do you feel it would help to suggest to him how his behavior is affecting you?  You could frame it in terms of "working on this together" to let him know you'll stand by him as he works on whatever it is that's going on.  Something like telling him "I want to help you feel better and have more peace."   Jerry is also right that without insight it's much harder for someone to even admit he has a problem, let alone work on resolving it.   You of course would not say "You make me so mad," you would say something like "When you act [insert behavior here] I feel [insert feeling here].  I want to help you."  Because that would alert the other person that they have hurt or upset you and hopefully they would then want to see how they can change to help get your needs met in the relationship.   That's about all I have for now as Jerry really was on target.   Regards, Christina
