Great posts!
Sorry if I led you to believe they were about him. Remember the 3 c's: You didn't cause it, You can't control it and You can't cure it. There is also the 3 G's: Get off of him, Get out of his way and Get onto yourself. I agree the boundaries are for you. What do you want in your life? Think. What is it that you want? What are you going to accept? Set your boundaries on that.
Food for thought....last year we took our kids to Disney. My RAH was in full blown addiction and I didn't know at the time. It was the trip from HELL. He had to be near the room, he had no patience with people, lines, even his own family. He was very aggitated or sleeping! We were all miserable. I finally left with the kids and did things by myself. I ask for a divorce on that trip! The kids still talk about how they never want to go back with him! It was a trip from hell with someone in full addiction. Just be prepared.
