What did I just do and what is she thinking now?

SKIP THIS BACKGROUND INFORMATION IF YOU DON'T THINK IT'S NECESSARY AND GO TO THE BOTTOM FOR THE MOST RECENT THING. This question might be tough, I can't figure it out.

I've known this girl for over a year now and I've always had a thing for her. It grew to the point where I fell in love with her. My old roommate introduced us because he was in love with her before. She wasn't interested in him but she slept in his bed every night. She's the type of person who says "I love you" a lot and always hugs and sometimes gives kisses when we drink.

1st big event was our heart to heart as she calls them. It was basically I love you, I've always loved you... back and forth. It was unexpected and I just thought she meant as friends.

2nd big event was when we made out. This is when I still lived with my old roommate. We were throwing a small party and I was sitting in a chair on the balcony smoking a cigarette. she came out and asked if she could sit on my lap... we were close enough that that wasn't weird, she'd done it before. When we finished our cigarettes, I was hugging her and we looked in eachothers eyes for a while and then we kissed for about 10 seconds.

3rd big event was when I told her I liked her and it was weird since we were friends. She told me I shouldn't like her. She then told me that she just wasn't sure right now. I don't know why she said that. I didn't ask her out or anything then.

4th big event was her falling out with my old roommate over a 300 comment facebook argument. They don't talk anymore and I don't talk or live with my old roommate anymore either.

Now, this semester, we live in the same apartment complex by chance.

5th big event was when I asked her out. I hadn't talked to her since she and my roommate had the falling out, we hung out for an hour once before I asked her out and then the next time I saw her I asked her out. Her response was, "You know I don't..." she was going to say date, but I interrupted her with something and then asked her out again. Her next response was "I just got out of this thing with this guy." I said goodbye and walked away, not planning on seeing her again.

6th big event was a month after I asked her out, she showed up in my apartment in my doorway in my room at 4 in the morning. she was drunk and she turned on my light and woke me up. I was cold and rude to her, but that's not how I really felt. I was honestly happy to see her. We smoked a cigarette together and she left.

I started hanging out with her again after that night.

We hung out more. She's a big flirt, fyi. We grew close to the point we said I love you to each other again.

7th big event was when I told her I couldn't be her friend because I like her too much. Long conversation and she said stuff like she doesn't want to lose me, I'm one of her closest friends, and "Is there anything else we can do?" she said that last one multiple times during the conversation.

8th big event was a week later I said I wanted to try to be friends again.

I finally introduced her to some of my friends. Now she hangs out with one of them.

9th big event was when I asked her if she wanted to hang out about a week ago and she said she was too exhausted. So I went to my neighbors' apartment to drink with the guys, and the one she talks to now went to her apartment to bring her over. I ignored her the whole night with one word comments whenever she tried to engage me in conversation. She eventually stormed out of the apartment without saying a word. She went to the pond and got in it. It's ******* freezing out.

I saw her the next day and let her know I wasn't mad at her.

2 nights ago I unfriended her and all of her friends on facebook. It was a random move, but my reasoning is that I'm done with her games. I know she likes me, her sister told me that both she and her sister like me. In fact, her sister tried to have sex with me one night but then told me that if I was crazy about the first girl I should leave.

What is she thinking now that we're not friends on facebook? Was that a stupid and childish thing to do? I'm just done with her games.
