I'm such a twat 😔

Ok so I don't drink often but tonight me and my boyfriend had a party. My boyfriend said I was flirting with some other guy, I was whipping him with a tea towel only cos he got me first. I just thought it was a bit of banter but no one seems to feel that way, he has a girlfriend who is the hosts best friend. I feel so bad I'm literally sat here crying, my boyfriends upstairs, he seems fine but he wasn't 10 mins ago I just want him to know that I love him and I don't think when I'm drunk I literally just do whatever but I would never cheat on him. The host and my boyfriend saw me doing this and the host asked me for the tea towel so I would stop. I feel so embarrassed how do I make it up to him 😩 also I'm sorry if this doesn't make sense
