I regret rejecting him. What should I do?

So last year around December this guy who I have mutual friends with decided to text me. He asked for my number over instagram and we texted and stuff. He was always so nice over text and always texted goodnight and good morning. But then he would barely talk to me in person. I was also super shy last year so that's probably why. He also told me he liked me over text but he said he was "on something" when he sent it so.. I didn't know how to feel about him bc we only started talking like a week at that point. It's kinda what scared me away. I also wasn't very attracted to him physically which ik is so shallow but whatever.. Then it was awkward after he texted me that and I told him it was okay and stuff. Then he asked me to the movies OVER TEXT and I completely rejected him. I'd never been on a date or even been alone with a boy. I said yes at first bc I'm too nice but then said no bc I freaked out hahaha and we haven't talked since. Then he said other friends were coming too after I said no 😂😂 He tried texting me after that but I ignored him. I'M SO RUDE AHHHH. I was just so shy and like reserved I didn't really know how to do that kind of stuff.

Now I think I like him again but I don't know. I feel like I just miss that attention and once I get it I'll get bored of it again, as selfish as that sounds. But I can't stop thinking about him, I feel bad that I might have hurt him. He still likes my insta pictures and stuff so he doesn't totally hate me.. But I think he and his friends do drugs and stuff so I don't want to get involved with that. I can't help but look at him when I see him and look for him when I know I'll be walking past him. But I don't think anything will be the same if I talked to him again. I've overcome my shyness a lot so it won't be as awkward if that makes any sense.. i don't know what to do. What do you think?
