Why did he stop responding while we were chatting on Facebook?

[Ste]

Hello guys.
So I "met" this guy online and we exchanged FB contacts. The next day he texted me first (I waited on purpose to see if he would have actually texted me after we met). We keep chatting for a while and then he suddenly respond slower, after 5 mins and then 15 mins, so when I saw he was doing that I responded to one his messages "oh ok I got it "(I got what he said). So after that he said: "yeep what are you doing cute one " and I answered what i was doing and i asked him the same. Plus I asked him if he had a Skype name. And then he stopped replying. I later said: you there........?
And he looked at the messages but didn't respond. It has been only one day, but still I think that's rude. Or maybe as many guys are, he didnt care: in that moment he was bored so he texted me and then he found something else to do and didn't respond to me. Or he was just bored about the conversation. It's just that 10 hours after he went off and on Facebook, that's why I don't understand.
He was at home.
Yeah maybe I am moving too fast, but still things should be easier, it feels like I'm walking on eggshells trying to do the perfect move.
