Boyfriend is ignoring me because i smoked weed with my friend.

Its almost my 21st. And I’m back in my home town for a bit. So i met up with my best friend thats I’ve been friends with for years. And we were drinking wine. And then we smoked together. Ive been high before with my boyfriend. But we ate a brownie. We didn’t smoke. And now he’s all pissed off at me because i smoked for the first time with my friend instead of with him. I don’t get it. He seriously stopped talking to me last night and hasn’t talked to me all day because of it. Like wtf. What should i do? Was i in the wrong? My friend is a female. So he wouldn’t be jealous or anything. And he smoked with my brother. Without me. Every time they’re together.

EDIT*** he did say he wanted my first time to be with him. But he didn’t specify my first time smoking. we got high together before eating a brownie. But he told me he wanted my first time smoking to by with him too. I honestly didn’t think he’d care. Since we’ve been high together before.
