i think i just wanna process my situation and hear some perspective from non-mono people, since all close friends I could talk to about this are mono. my primary partner and i opened our relationship a while ago and i've been seeing another person for a few weeks now. we've mainly been having sex, but we also started talking a bunch outside of that because we get along. i guess we are best described as friends with benefits? we both have boyfriends.

they are properly poly, i view my boyfriend as my primary partner.

ive met the boyfriend of my fwb before and i honestly have a massive friendship crush on him. i just wanna be friends with him so bad holy shit, he's just a geniunenly super cool dude. but ive never interacted with both of them at the same time. my fwb and i have a physical relationship and we also casually kiss when we hang out and stuff. me and the boyfriend are just homies. they invited me to have dinner with both of them tomorrow, and i have no idea how to act about it :') do i kiss my fwb as a greeting like i usually do? is that strange to do in front of their boyfriend? do i just make this a dinner with friends thing and ignore that im sleeping with one half of the couple? i usually had stuff with single people or couples with DADT arrangements, so this is all new and exciting, but also scary to me. i know everyone is different, but is there some sort of etiquette here? (my boyfriend knows and is rooting for me, but he doesn't get why this is confusing to me lol)
