Love through an online game?

It was Wednesday, week 4.
it was test week for me and since I don't study REALLY much I decided to play some garry's mod and play in some servers.

I think there were no good servers, so I joined a server on a level called rp_downtown_v2 with only one player in the server.

So we started to talk, I found out the player was a girl. She had a spray(a picture that you can put on a wall) and on that spray was her picture. I remember telling her that her hair was like 70's style. :) She asked me to add her in friends but I said no because I hate having much friends...

Boy am I glad that I added her even though I said no...

For some reason, I had a blackout. I now can't remember much of what we talked about, but somehow, I have no clue how, I'm saying the truth. I actually fell in love with her. Well because of my previous experience when I fell in love with someone(she laughed at me, she told all her friends and then they all laughed at me and that made me feel sad) I didn't have the guts to tell her. So I was like with her in the game, I was kinda happy and suddenly she found out somehow in my behaviour to her. I remember her saying:
"OMG you love me!"
At that moment I almost shat my pants. I talked and sang through the mic all the time, that's probably how she knew... but when she said that, I couldn't talk through the mic because I was shit scared. So the only reaction I could give was: ":O"

That's right, I couldn't say more than :O, and she went on asking about me, hell I didn't know what to do and after a while she got me to confess...
I told her and of course I was afraid she'd laugh and turn me down...
she didn't.

She started drawing a heart with ropes saying she loved me. I was happy, I have never been so excited in my entire life. We both made hearts with ropes and that was a really nice experience. After a while she had to go away from her keyboard for some reason, leaving a soulless player in the game I was playing. Her character was standing in a corner in the sewers of that level. I started making a kind of forest for her, and at the end of a forest/maze, she'd find me with a heart drawn with ropes saying I love her so much. I told her through the "steam chat"(The ingame chat program) that she'd have to follow the path of the hearts and she would find me.

Later, after that game we talked a lot through steam chat and we said nice things to each other.

A few days ago, I told people at school. They asked me "Do you want to go to the city to find some chicks?" I, as stupid as I am, said that I already had a girlfriend. The moment I said that I felt like "oh shit". That was during a study hour at school. Apparently it was SO special that within half an hour, REALLY a lot of people knew. Someone I had in my class like 4 years ago suddenly walked to me and wished me luck with her.

The day after, friday, my girlfriend was really silent, she didn't say much.
I asked her why, she told me she was tired. I asked why she was tired but she told me she didn't want to talk about it. Saturday she was even more silent, she built some things in garry's mod but she seemed sad. She said she still loves me though, and she still said nice things, so I don't think it has something to do with us being in love.

That sunday I had to go to my family for some birthdays. I was home late but I found out she hadn't been online all day, the day after she hadn't been online either!
I know that she games a lot(about twice as much as I do) and that being away for two days is really weird for her.

I'm starting to get worried. Could something have happened to her? At least I'm sure she hasn't blocked me, she would never block me without a reason and besides she's been offline so long for other people I know too...

I'm making this post because I miss her really much and I hope she'll come back soon!

EDIT:
She's back :D
