relationship advice PL

So this guy seems like he likes me, like he was always being super supportive and going along with whatever crazy idea I had. He would send me notes saying ‘I miss you’ and would sometimes throw his hat across the room to me so he could go up and talk to me. He would also sometimes blow me kisses. I asked him out to prom and he was like ‘yeah..’ like he seemed hesitant but I was like a yes is a yes right? We see each other the next day and he seems pretty excited and winks at me. THEN he shows up for like half an hour, leaves, and doesn’t come back til super late when it’s like almost over and everyone’s done.
He tells me he had fun seeing me but then
“I’m not ready to be in a relationship right now. We should just stay friends.”
Ok so now it’s June and I decided to start posting on TkTk and you know those like ‘glow up’ transition ones where u start looking kinda bleh and change into like a formal dress? I’ve posted those. And like vids of me in my bridesmaid dress which is the cutest. AND HES LIKED MOST OF THEM. He’s the only guy who has. And he once commented!
