I have a crush on my boyfriends best friend

So I know this is going to make me sound like a terrible person... but here goes. My boyfriend and I have been together for 7 months now. He’s absolutely amazing and I’m seriously so lucky to have him and care about him more than anything in the world. I would never do anything to hurt him.

So here’s the terrible part, I met his best friend for the first time over the weekend...and now I can’t stop thinking about him. We got along so well and I felt myself really attracted to him. (I haven’t had these thoughts or feelings about anyone else other than my boyfriend during my relationship with him) now we have plans with him twice throughout this week and I’m excited to see him, but incredibly nervous as well. I would never act on this crush towards his friend. I love my boyfriend. I’m just so confused on how to handle this because it’s incredibly awkward. I have a feeling his best friend might’ve felt the same way, possibly. There was just a lot of tension there.

I read a few articles online that this is actually a pretty common thing. Just wanted to get some thoughts and opinions or personal experiences. Please be kind! I already feel bad enough about it.
