Who’s wrong?

So my boyfriend gets off at 7. Texted me at 6:30 wanting me to get him a drink at a store. I told him if he could wait so I don’t have to leave because I’d rather not have to unless it’s for work or a grocery store. He gave me shit for it said it’s sad I won’t do anything for him and it upsets him. That he does everything for me and I don’t do anything for him. All because I didn’t want to get out and get him a drink when he gets off in 30 minutes. Could I easily get him a drink? Yes. I don’t want to because I want to follow the rules on only leaving the house if it’s essential. IMO that’s not essential.
