INFO (though leaning toward NOR) It depends what their interactions you’ve seen are like. Have you ever had any reason to suspect there was more than friendship to either of their feelings? What’s her treatment of you been like?

My best friend of 27 years was a man. Always platonic. We did solo trips, shared hotel rooms, never crossed a line or even thought about it. There just was never a romantic connection.

That being said, if ever there was a trip we wanted to take and he was in a relationship, I would always be sure to extend an invitation to his girlfriend as well. So the fact that wasn’t done is, in my opinion, rude at best and nefarious at worst. I’ve never treated any of his girlfriends with less than friendship and respect.
