is my FWB getting attached?

Al

I don't wanna bother my friends by talking about him constantly so I'm ganna go off on here. So I first started hooking up with this guy 3 years ago and everything was fine, normal FWB relationship, but then I started dating someone do we stopped for 2 years. we work together and his car is in the shop so he asked me for a ride home a few weeks ago, I get parked at his house and he starts telling me about how he was this close to just asking me to date him but then I started dating my current boyfriend. said he missed me and everything then he kissed me. since then I've been cheating on my boyfriend with him but it's so weird this time, things are different. he wants to hang around and cuddle in our hotel room, he introduced me to 2 of his friends (fwb shouldn't introduce you to their friends??) he texts me every day (not sexual things just random shit) and starts the covo 90% of the time, we just sit in the car and talk for hours about nothing, he buys my dinner when we go get food after hooking up, he tells me to look at him when we have sex so he knows I'm thinking about him, and it all just seems more to me like he has feelings for me (which I admittedly have for him as well but I have a boyfriend who I'm not just going to drop for him.) He's moving 3 hours away in 2 months which is why I'm so confused as to why he's acting like this, he's even gone as far as to tell me TWICE that I should just leave my boyfriend and spend these next 2 months hanging out with him instead. can someone tell me wtf is going on please I'm driving myself insane trying to decode this guy
