Ok, I finally did it...what now?

Ok so last time I was talking about how to talk to the guy I like OUTSIDE of schol. wellll today I finally did it on facebook, every single day i see his name and i stare at it and finally i just did it i started to talk to him and we spoke for a long time about a bunch of different things and towards the end I guess he didnt know what to say and then after a minute he just got off, so idk do you think it went well? Im glad I got to learn new things about him so what should I do now like wait for next time he gets on talk to him? He is extremley shy so Im the one who came up with most the stuff to talk about but he did pretty good. btw we are both 15.
