'xx' at the end of a Facebook chat, what does that mean?

[awesomelycrazy]

Ok, so there's this guy I really like. I go to an all girls school, but I see him once every week at this tutoring place. I don't really know him all that well, and I have only DIRECTLY spoken to him once. Anyway, yesterday I was talking to him on Facebook chat under the pretext that I was bored, and he was fully involved in the conversation. At the end he put 2 kisses (xx)...

I was wondering if that means anything? I don't know if he does that to anyone else...maybe he does, but guys, is that a normal thing to do? WHat does it mean?

Thanks in advance everyone :D

It is a simple flirt that can be taken seriously or not so seriously. You will know how serious he is "into" you in no time.
