So, I need some advice

I think my boyfriend of 2.5 years may have a drinking problem. Now don’t get me wrong he’s great & I love him. He’s not abusive in any way. A little back story, he’s 29 and his dad growing up was an alcoholic 😔. He drinks quite frequently. Pretty much every day after work (he does have a job) . I understand some people like to kick back with a drink after work, I get it. But he always seems to drink. He has a motorcycle that he rides to the bars. I don’t really like that bc I think it’s dangerous. I can’t control him and he assures me that he’s not drunk when he rides his bike. I always tell him not to drink too much and I always ask him how many he’s had when he gets home. He always says just like 4 beers (he only drinks beer at the bars or when he’s out never liquor he rarely drinks liquor and it’s always a mixed drink at home) But he has to mindful that he has a very high tolerance so I feel like he doesn’t understand that just because he’s not “drunk” he’s still probably above the legal limit if that make sense. I’ve tried talking to him about but he doesn’t think he has a problem. He drinks pretty much all weekend every weekend wether that’s at the bar or at home. Weirdly enough I can never tell when he’s drunk or if he’s drunk or not, no slurred speech, no stumbling or falling, no yelling, no crazy behavior or puking. So idk if maybe I’m overthinking and overreacting and this drinking isn’t a problem?! Opinions?!
