It might be time for your husband to attend Alanon meetings to learn how not to be co-dependent. We went through this for years with my middle son who has a drug addiction. He has been homeless more than once and is now. Both my ex and I will talk to him on the phone but have made it clear he can’t live with either of us and we are done sending money. It’s heartbreaking and the hardest thing either of us has ever had to do.
