What do I do if my Boyfriend is Ignoring me more and more?

Anonymous
Okay so a little context, me and my boyfriend haven’t been together very long (only about 4 months or so) and it was very obvious before we started dating that he had a massive crush on me. No matter how much he tried to hide it, I knew. He would text me and snap me 24/7 and gave me all the attention in the world.
But once we started dating about 2 months in, he started leaving me on delivered for more than 10hrs at a time and when he did reply, it wasn’t very big of a response and the conversation would end pretty quickly. He never asks me to go anywhere with him anymore, he never talks to me in school. Like sometimes when I pass him in the hall he just doesn’t even notice I’m there.
I just feel like I’ve upset him or done something wrong but I have no idea what. Ever since our last date, it’s very hard to even get him to open my message nevermind respond to it. And before people say “well you should talk to him about it, tell him how you feel”, I have already done that and he just brushed it off saying that sometimes he’s too busy or can’t be bothered to respond to me. I’m not sure he meant it like that but that was basically what he said. I also feel like if I asked him about it again he wouldn’t even open the snap. The relationship feels as though I’m the one who is putting in all the effort and I feel like he's fell out of love with me but doesn’t want to say. I have asked if he still loves me and he said “of course I do”.
What do you think I should do? Why is he doing this? Also, I don’t want any blunt responses, if you’re not gonna say anything nice just don’t respond to my question
