My partner often suggests we start drinking again.

My bf and I quit drinking within days of each other 1.5 yrs ago. We split briefly but got back together with the understanding there is to be no more drinking. Not even one drink. He agreed. Well, on numerous occasions he has suggested we drink beer, wine, whatever. I go ballistic when he suggests this. I tell him he can leave if that's the way he wants to live. He has made statements that lead me to believe he thinks he could control his drinking if he started again. There is a lot more going on in our relationship but I'm choosing this to share now bc I feel he will eventually start drinking again and I'm afraid. Even though I've been sober for 1.5 years, I only go to meetings sporadically. I rarely speak. It's bottled up inside and I see I need to change. I need to hear from others who have been there. What should I do?
