Boyfriend's best friend hit on him while I was away

Last week I went up to visit my parents and get my wisdom teeth out. During that time my boyfriend messaged me all upset one night saying that he invited his best friend over and apparently when they were on the couch he tried to cuddle/lean on my bf. And my bf freaked out on him. His best friend is bi, but leans more towards guys. Ever since it's been awkward between them.

Idk I don't think it's that big of a big deal. It's not like he tried to kiss him. His friend later apologized and wanted them to go back to normal. I told him if the friendship means that much they should continue to stay friends and forget about what happened, but also tell him not to do something like that again.

Lol also idk if I should be mad cause I'm friends with him too and he knew I was out of town and did that. But I don't see him as a threat. My bf's annoyed cause I teased him about it and wasn't really phased.

What do you guys think?
