I finally started talking to the guy i like on fb a few days ago..?

I think you guys have a chance, but I don't think he likes you yet. Get to know him first. Wait a day or two before you talk to him again, and give him your number so you don't just have to talk on Facebook. Make plans to hang out. Just take it slow. Flirting can turn into actual feelings, but not if you rush it. Good luck and have fun (:
