Welcome Anita. I am glad you are here and posting , because so many people here will be able to share similar situations with you, believe me.
I am sorry that your husband is being abusive and using drugs. I can understand you not wanting this to be your life.
There are stories here posted for new comers to read.. called stickies... located at the top of the friends and families of substance abusers page.
I wish I could tell you whether he will ever see the light. He might. but the abuse, that is part of who he is, I am afraid. NO one deserves to be abused in any way.
I am glad you are here and you will find some awesome support from the folks here.
