I really like this guy but I messed up everything 4 months ago. Please help?

So i started talking to this guy in my freshman biology cl over the summer and I started to like him a little. When sopre homecoming was about a month away, rumors got around that he was going to ask me, but before he did I told his older sister that I didn't think I liked him. I was getting over another guy and I didn't want to hurt him by going on a sympathy date. Now he is in one of my cles and we talk pretty much everyday. I don't know if he likes me but I had a meltdown the other night and cried for about two hours because I couldn't believe I had hurt him the way I did. I regret everything that I said a long time ago, but I don't know what do do now.I really like him and a small part of me always did, but I've never had a boyfriend. Advice?
