Idk what to do!!!!

I’m in a casual relationship with this guy. He’s literally so fucking cool and awesome and hilarious and out of my league and I’m basically head over heels for him. At the moment I really can’t think of being with anyone else. But it’s a casual relationship like I said, and being the dumb bitch I am I let myself get attached how fun!!!! But i really don’t think he feels the same way. He’s told me he’s not ready for a girlfriend and I get that and of course I don’t want to force him into anything. And lately we’ve been talking a little less and I’m scared it’s basically over but I seriously like him SO much and I’m stressing all the time about if he doesn’t want to be around me or likes someone else idkkkkk. What should I do?? I want to talk to him about it but it’s awkward af and I already knows how he feels about the girlfriend situation so idk what that would do besides make both of us uncomfortable. And i cantttttt just forget about him because we still talk and stuff and I’m just too hopeful that something will work out eventually. What should I do??? It’s sad and pathetic lmao I know but I just caught strong feelings for him
