Do I move on or is there something there(10 points to best answer)?

So over a year ago me and this guy started talking,we talked for a while,i was a sophomore and he was a senior in hs at the time,he smoked,drank,and isnt a virgin,im the complete opposite of that it was going good then he just stopped talking to me,then a while after I talked to his cousin &he was like yea he liked you but he thinks you're too innocent,i didnt really understand what that meant,i liked him for a while after nd then i finally got over him after a while.then one day i was at lunch with my bestie nd i saw him and he was staring really hard but i didnt wanna think to much,then later that day he messaged me on fb talking about wanting to talk to me again nd how he feels like a dick for not talking to me.so we talked and it felt like we never stopped talking and my feelings kind of came back but i had a guard up.we've gotten to the discussion about sex one night(ibrought it up)and talked about becoming fwb.but never really became them but we still talk,hes had a gf and ive had a bf during the time buh none of them lasted long.I dont know why but hes the only person icould see myself having sex with but,idk,i dont think i like him buh idk &idk if hes in it for the sex or what?its been over a year and nothings happened between us.ive wanted to ask him how he feels about us but ithink if there was he wouldve said something,what do i do?
