Just need to vent...

My heart is hurting... My husband has a substance abuse problem with marijuana. He smokes everyday. He also drinks once and a while. Our religious beliefs teach us other wise. I'm a Sunday school teacher myself and I have recovered from these problems. I don't know what to do other than pray for him. Anytime I bring it up he verbally abuses me and gets so mean. Sometimes I loose my temper and say mean things back. It's illegal where we live and he does it at home and work. I'm worried about him.
