Guy Advice? Please Help?

There's this guy I think I may be in love with. We used to talk but it was never official. We stopped talking a month ago because of some things that I regret doing. I can't seem to shake him and I find it funny that when he first gave me a ride home he ended up living in the neighborhood directly across from me. I tried texting him how I feel but he still hasn't answered. I'm really worried because he's the type to get into trouble though he's extremely sweet. Any advice? Should I let it go or no?

P. s- we used to work together until he quit but we still were talking after. I'm 17 by the way and he is a bit older than me.
