Welcome to SR but sorry to hear about your husband. My husband is my addict too. His drug of choice is cocaine. I found out almost two years ago that he was using. I just moved this past weekend (not that this is the best choice for you). SR helped me find my way.
My only advice is to come here often, you will get great advice and support. Also, read the "stickies" at the top of the SR Forum page especially "What addicts Do" they are very helpful!
Prayers,
Tiffany
