Screwed up and unsatisfied

[UnSaTiSfIeD]

Ok, so here's the story.
I met a girl a couple of months ago.
We got along quite well.
We like to disturb each other and it was fun.
Then when I realized she is from other country I got confused.
Reason being she treat me differently from other people and she started showing signs of interest towards me.
I was/am a coward.
One day, I asked her whether she had feeling towards me.
She said no and asked what if yes.
Then I stupidly (this is when i screwed up, big time!) answered "i treat u like a sister"
Yes, i know how bad and serious that answer was.
After that she started getting closer to my guy friend.
I started feeling jealous and this is when I realized how much I love her.
One week after my stupid action I confessed to her.
I was so jealous and confused and so much things was in my mind.
At that time confessing seems to be the best thing to do.
The girl and my guy friend got closer and closer and when I chat with her I raised this issue (the jealousy and what is with her and the guy)
So, she decided to talk about this face to face.
We met 2 weeks ago and settle this thing.
She apologized to me and said :
"I want to protect someone. He is like a kid to me"
I asked her is that person my guy friend.
She nodded.
Few days ago, my female friends asked my guy friend is he couple with a girl who was sitting with him at the foyer.
According to my friends, he said "I haven say yes or no yet"
I know I am nth but her normal friend now.
Our conversation is short.
I know I should let it go.
But I don want that guy to be with her.
He flirts with girls.
He disturb girls as if he likes them.
I hate that.
Seeing him do that to other girls make me even harder to let go.
I really hope they will not get together or will not be together long.
I know I must let her go and live my life.
She is happy now.
I should be happy too but my mood and emotion are still going up and down.
Almost everyday when I wake up I think of her.
I want to get her back but I don know how.
At the same time I know I should just go and look for other girls.
Please help me.
I am unsure what I should do now.
I know nth about how to get a girl's heart and love.
And I am not good at making girls laugh.
Especially in front of the girl I like.
I tend to get nervous.
Please help me. Give me any criticisms, comments, opinions, suggestions etc.

Ok what you said was pretty damn stupid, i mean if she had feelings for you and after you said that you basically rejected her flat out cold. And it is possible to make things right with her, im assuming you told her that instead of her being like a sister she was more than that and that you wanted a relationship with her, just give it time and try to get close to her again, and stay away from telling her about your friend and how he acts, if you tell her and she sees it all that is gunna happen is that your gunna be a know it all big brother to her, and you will ultimately lose her.

The problem is I have no idea how to get close to her. All I know is start by chatting with her in msn as often as possible. But so far, in the around 5 conversations we had, all 5 are short conversations. I don know how to start interesting topic. Sometime I feel that maybe she is just not the one. But I'm the kind who think too much. And I don feel like giving up even though most people and part of me say I should.
