Is my boyfriend alcoholic?

I’ve (F23) been with my boyfriend (M26) for almost a year, and I’ve started to feel concerned about his drinking habits. Before we met, I drank maybe twice a month—just socially, with food or friends. Now it’s more like twice a week, which is fine, but I still don’t drink to get drunk.

My boyfriend, on the other hand, almost always drinks to the point of being drunk. He rarely stops at just one or two. It usually starts with a beer, then moves to vodka, wine, etc., and keeps going until late at night. He only stops when I say I want to go to bed.

Last week he got drunk four nights in a row. A lot of it is tied to social stuff—watching football at bars with friends—but even after the game ends, he keeps drinking. He’s not aggressive or mean when he drinks (he’s actually really sweet), but it feels like he doesn’t have an “off” switch.

I’m worried—not just about his health, but about what this might mean long-term. It feels like he drinks to his limit every time, and I’m not sure if that’s normal or if it’s something I should bring up.

Has anyone been in a similar situation? How do I talk to him about this without sounding like I’m trying to control him?

TL;DR: My boyfriend drinks to the point of getting drunk almost every time, even multiple nights a week. I’m worried about his health and wondering how to talk to him about it without seeming controlling
