Am I dating someone without knowing? (lol @ my life)

So I've been hooking up with this guy for a little over a month since I've gotten back to school, but I literally don't know what we are at all... he buys me food, has taken me out to dinner, went to my favorite college bar with me and bought me a drink/let me steal his, we have sex and hook up, but it always involves a lot of kissing and he wants to cuddle after. He's slept over before, we text or snap chat constantly, etc... so I thought we were just going to be FWB but I feel like it may be more? But at the same time I don't know if I'm just thinking it is more than it is? Any answers would be amazing 😊
