Drug addicted husband

Hello,
My husband is addicted to ICE but has taken all other illegal drugs also in the past. When I first met him he smoked marijuana but then in the last 10 years started using harder drugs.

He would have episodes of hard drug using for days in a row and would disappear and stay awake for this period of time. He also has periods where he seems clean (I think? as his behaviour seems normal).

Of late he has started again and when he does he hates everyone but normally I am always his punching bag (not literally) he would be very abusive verbally but has never hit me but I am scared that may change.

I did leave him several times but have come back because I feel sorry for him and because I know he is normally a very nice person but these drugs have changed him, plus we have 3 children who love him so much.

I don't know what to do, I want to leave but again have this idea that maybe he will get help and I try to drill that into him over and over but he keeps denying he has a problem then turns it onto me somehow and how everything is my fault.

What should I do?
