Hello Dee: I'm sorry you are in this most difficult situation.

Personally, I don't think any of this was your fault. This man has a boatload of problems & a penchant for putting it all off onto someone else... you. I'm not a psychologist or an addictions expert either. So I can't say whether how this man is acting is all related to the drugs or if there are perhaps some additional mental health issues going on here. But, to some extent, from my perspective, it really doesn't matter. What matters is the way he has treated you.
From what you wrote, I'd have to say my personal opinion is you're best off without this man. If he really has cut you off permanently, he's done you a huge favor. Accept it with gratitude. If, on the other hand, he does try to come back into your life run in the opposite direction!

At least that is my perspective... for what it's worth...
