I was in a four year relationship with an alcoholic. He left me and I don't want him back.
Was it bad when he was drinking?
Well, when he drank, I wouldn't see him for days.
It sounds like you did the right thing not wanting him back. You will be happier without him.
I'm going to miss him.
I'm sure he had good points that you'll miss. But when a relationship is that unhealthy, it's best to move on. I hope that you find someone who treats you better soon.
