18 and never had a boyfriend?

Im 18 and a freshman in college, and i have never had a boyfriend. I know guys have had crushes on me and feelings for me, but i only considered them friends and didnt want anything more than that. Guys have hit on me and always ask me to dance at parties, so i think i must be somewhat attractive at least. In high school, i never felt the need for a boyfriend; i was happy being single. recently however, I have liked this guy. we became really close friends and i had never felt this way about anyone before. I recently found out that he didnt like me back that way, and it hurt me so much, and my self esteem is pretty low at this point. as much as i hate to admit it, this guy has made me reconsider myself a lot and doubt my worth. i just feel like i will never be in a relationship and never have a boyfriend. it takes a LOT for me to like someone, and after i made myself vulnerable for this guy, i dont think i will ever be able to do that again. but at the same time, i really want a boyfriend right now because i feel like i should have experienced this by now. that desire could be because i was just "emotionally broken up with" but i dont know. I also am still waiting on this guy a little and hoping that, now that he knows i like him, he will start to develop feelings for me too. Should i just move on, or wait a little? thank you!
