How do I get over a one sided friendship

Dude this guy is so nice, he’s smart and chill but I think I’m too much for him. Sometimes he never responds and I get so sad or if he doesn’t continue the conversation. I just wanna know stuff about him and when I find out stuff he doesn’t ask me. It feels like I’m the only person putting in the effort, I guess some people aren’t as social. He is a genuinely great guy though, he’s just terrible at texting. It makes me so lonely and sad.
