Ugh please don’t judge me

I need advice...

My boyfriend and I have been living with our roommates (a gf/bf couple) 2/3 months now and we took molly all together. It was honestly the best experience I’ve ever had, I feel super close and bonded with them now. However I have to confess, I’m now torn I don’t know how to fully decipher how I truly feel for my roommates. Specifically the girl, I think I might be attracted to her in a romantic way but idk for sure. It’s hard to tell considering I’ve had little to no close female friends and I’m pansexual. However the way we interacted felt romantic and she held my hard in hers to point out a freckle and called it a soul mate sign. Maybe I’m just easily influenced idk, I feel awful tho because I adore my boyfriend and I’d never want to leave him. But every day I spend with my roommates brings me another step closer to craving a polygamous relationship with all four of us. On the bright side my boyfriend said he would totally be into a poly relationship with me however I haven’t told him about how I felt yet because idk exactly how I feel yet. Ugh I’m so torn someone help me map this out
