exCordis,
Sure sounds like the whole family is in pain from his drinking. You sound like you have a pretty good idea of what life will be like for anyone closely connected to him. You were strong, and I was glad to hear that you "dont do breaks"- good response! Self esteem will take you a long way .
I hope that his family gets help.
Rejecting his behavior will do more for him than anything else you can do. Hope it will be a good wake up call for him.
Take care of yourself- you seem to be doing a good job of that, and that is all you can do for him.
big hug,
chicory
