Are you afraid that having him around will trigger you and thwart your efforts? You have to do whatever necessary to protect you right now.
What do you think is going to happen if you have a discussion with him about it? That's the key. Either you're going to find out that drinking is more important to him than your relationship or you may find out that he feels the same way about his own. You'll never know if you don't talk about it.
Your post leads me to believe you already know the answer. It all depends on how invested you are in the relationship and if you think it can survive the absence of alcohol as a shared factor.
At the end of the day the #1 priority has to be your sobriety and recovery. I hope all goes well.
