Fighting with boyfriend

Okay so I don’t ever drink unless it’s a party or vacation and the other day I was drinking vodka and lemonade and my boyfriend got all pissy and tried saying I’m not allowed to drink like okay just since you and your friends can’t handle your alcohol doesn’t mean I can’t and we haven’t even been dating a week so don’t try and tell me what I can and can’t do already like he used to vape and occasionally still does and I don’t like it but I’m not gonna tell him he can’t do it 🙄 I get him not wanting me to drink a lot but it was only one cup so I don’t get what the big deal was
