Set-up?

I got mad at my boyfriend and left a party. So,his friend ran after me and tried to talk to me. I thought he wanted to take me back,but then he asked if he could kiss me. I was shocked. He tried to kiss me and I left. Now he's telling me he likes me and wants me to come over to his place. I have a feeling this is just a plan or set-up to see if I'd do that behind my boyfriend. I don't know what to do or how to tell my boyfriend 😥😥
