started as nothing but does he want something now??

okay so I've been hanging out with this guy, everytime we see each other we hang out for a little bit and then have sex. he always asks me to stay the night before anything happens and we cuddle until we both wake up and eventually I go home. it's about every 4 days he wants to hang out. I'm being patient to see if maybe we get like a thing going on but I'm going insane! he tells me I'm completely different from other girls! "I don't bother him about being serious when he does hit me up I don't get pissed and say he's using me for sex" the last time we were chilling our convo was leading into something that went like this: him: "I just like hanging out with you. sex is just a bonus" me: "I just like being friends with benefits with you" him: "honestly if you wanted to come over and not even have sex I'd be like sure come over" me: "uhh yeah isn't that what friends do?" then he kinda mumbled and sounded butt hurt or something. like, I feel like he doesn't know if he wants to be an item or not..and I really him but I'm keeping my distance just in case he doesn't. what should I do! what do y'all think? is he confused or jyst playing the game better than me?
