Facebook chat girl 10pt. Best answer?

[Steve]

I'm on school holidays I'm in year 9. I have classes with her

There's this girl I like and I talked to her on Facebook at 11pm it went like this I my friend actually sent this (hey x)

Hey x
😮err sorry I left my phone at my friends for a few days!! I am so sorry about that!! At least it's only one message

Haha it's ok

Ok I'm just not so sure what "x" meant I just thought it meant kiss or something and I was like aaaahhh

😊 ( it's a smily face)

I'm kinda dumb with that kinda stuff

Yeah me too

(She went offline for 30secs)

Hm, I have to go sorry going to bed

Ok bye

That's the end

She did go offline for the rest of the night after saying she had to go to bed

I am quite shy about relationships I have never had a girlfriend

I sent her a message (hi ) 2 days ago she came online and read it then went offline, what do I do from now?

She always comes on for 5 mins and goes off since I sent the message
