he asked was I falling in love

ladies please help I need some insight on this.. so i’ve been having sex with my SO and the last time we had sex last night in the middle of it he randomly asked “you falling in love yet” and I do like him a lot we just haven’t said that yet to each other. we’ve been dating for a few months now.. I asked him earlier about it and he says “It slipped out I didn’t mean to ask that idk where it came from” like what? how does that type of sentence slip out of your mouth? lol.. what do you ladies think? I think he’s a little embarrassed by asking and wasn’t sure if i felt the same or something i’m really lost with how he feels at this point
