help please

i posted this yesterday but didn’t get any responses, so i’m trying again because i’m feeling really anxious and stuck in my head. if anyone can take the time to read and respond, i’d really appreciate it. i’ve been with my boyfriend since september and i care about him a lot. in january, i went to my best friend’s birthday party. there was a guy there who is part of her friend group. i had kissed him a couple of times while drunk at parties a long time before i ever met my boyfriend. before i started dating my boyfriend, that same guy once asked me to come over, but i said no because i regretted those past situations and didn’t want anything like that. he was fine with it, and after that we were just on friendly terms, though we never really talked outside of group settings. at the january party, he was there and asked how i was doing and if i had a boyfriend now. i said yes, and he asked how things were going, and i said good. throughout the night, we had normal group interactions. he asked me about an anime, and in general we just had casual conversations. however, some moments were playful in a group context. for example, i took a stuffed animal from him as a joke and ran off with it laughing a couple times because it’s an inside joke in our friend group, and later during just dance i playfully swung my arm out at him as a joke. i also apologized to him when the topic of someone he knows having cancer came up. i want to be clear that i had no romantic, sexual, or flirtatious intent at all. i was drunk and just being more outgoing with everyone than i would normally be sober. afterwards, he left and nothing else happened. i didn’t tell my boyfriend because it felt like a minor, meaningless interaction at the time. but months later i’ve started feeling really guilty and like i did something wrong or betrayed him. my boyfriend is sensitive about people from my past because of his previous relationship, so i’m worried he would be upset or think i cheated or acted inappropriately. now i keep replaying it in my head and it’s affecting how i feel even during good moments with him. so can someone please tell me if i did something wrong? i just cant handle the fact that if he knew he might be upset its driving me crazy.
