You can certainly let him know how you feel, but you cannot force him to accept his addiction and/or seek help. Leaving is certainly an option too...abuse is abuse, whether it's verbal or physical. And in my opinion it's completely inappropriate ( not to mention illegal ) and you need to think long and hard about what the relationship actually brings you and your daughter.
That's not to say that he has no chance of recovery...you have found a way to recover and so have lots and lots of people. But it has to be a decision he makes...and you need to be prepared that he may not. That means protecting yourself and your child.
