FML...I'm catching feels

Got with this guy I knew from a couple years ago but he didn't know me. It was supposed to just be a hook up and I literally am catching feelings and I don't fuckin get it...this does NOT happen to me. I don't know what to do 😩😩 and don't think a relationship is a possibility because believe me, definitely isn't the time for either of us. And I definitely cannot confess I'm catching feels lol
