Anita,
Verbal abuse is like a smack in the face. His family is only seeing 'his needs' and no one else's. the apple does not fall far from the tree,perhaps.
He does not want to quit pot. He will ignore your needs, and wish you would just shut up and let him do what he wants. Well, you are a human, and not a machine to be programmed for his convenience. You have feelings. He isn't considering those, because he is an addict and that is what they do.
Ignore his family if you can. When he is on a respirator someday, they will maybe see the bigger picture. It happened to someone I know.
you will find support from many, and I am glad your friends and clergy understand. that is all you need.
