Me(18m) and my bf (18m) and... My friend?(18m)
OK so I have a bf, I'm happy with him, we are in a open/polyamorous relationship. Me and him are getting much more of a wholesome and words of affirmation but... Recently I've also been into this friend, he's fun and Idk me and him just kinda click. He goes to my performances and I am teasing him like today I was attempting to put glitter on him in a way that felt weirdly flirtatious on my end and I am scared I may be into him but like, near others he said no to glitter but I asked him over text and he said maybe which is new because he is pretty stubborn when he says no. He went to my performance the other day and we aren't even too close of friends to the point he couldnt just not go but he went despite having gotten very little sleep to the point he was falling asleep standing. And him and me kinda tease each other like sending silly jokes to each other. And the other day me and him were talking but not the type of dumb calling people femboys type of thing but like silly lighthearted banter. Ik its a poly I'm in but why do I feel guilty for maybe liking him too? Like me and my bf are happy and doing great but... Idk. I need help. Am I dumb and overthinking? Edit: Am I also bad at knowing when someone is just friendly?
edit 2: for some extra context like I said me and my bf are polyamorous and are open to dating multiple people at once and I still really love my bf I'm just scared I may start liking this friend because I am able to like multiple people at once from time to time, like I can like one person and another at once. Idk I meant to say this earlier but never remembered to.
