Was I overreacting to my boyfriend's action at the New Year's Eve party?

On New Year’s Eve I was at a party with my boyfriend. Everyone was getting drunk including me so I was over emotional. I cry easily after I have fun. Anyways, there’s this girl that is somewhat attractive but kind of ditzy. She was with her new boyfriend.

Anyways, I was standing right there when my bf told her to try his burrito. She took a bite while he was holding it and asked, “Is there meat in this? I’m a vegetarian.” She mostly got rice but there was a piece of meat on her chin…and my bf took it off and ate it.

I was really upset b/c feeding someone and taking meat off her face n eating it seemed kind of a “more than friendly” type of thing. Then I saw him going around feeding people his burrito so I let the hand feeding thing go since he went around trying to get other peopel to try it.

I talked to him (while we were drunk) and he said it was no big deal and that she had meat and he wanted to eat it.

A week later (us sober), yesterday he didn’t remember doing that. He remembered her but not that moment that I got angry over.
