What kind of person is she to do this to me?????

Hello world, I just want to get your opinion on this. Everyone has the one person they see and think wow I would love to go out with that person or just have that person talk to you but deep inside u feel like they never will give u the time of day. Well I found that girl and she gave me the time of day and made me feel great. Everytime I would talk to her everything would be perfect, we both like the same things in life. So after about a good 2 weeks of talking to each other I say something about goin out but in my mind Im thinking she wont go out with me I havent known her long enough, but to my surprise she said sure. So Im feeling like I can fly, Im just so happy because the girl who I never thought would give me the time of day is goin out with me. When I see her she is so BEAUTIFUL that suddenly I feel like Im in a dream because in my eyes she was perfect. And where I live we have something called the Boardwalk and it has everything you need at a date you know Dinner and a movie. So we hung each other and we walk around until our movie was about to start. I paid for her movie because I just didnt feel right with her paying. So we get in the movie and shes just is looking all in my eyes smiling and blushing and I can't help but smile back at her. And one mistake I think I made is that she go real close me while I was looking at my phone and she was like a inche from my mouth, so In my mind I said if she does that again Im gonna kiss her and I did.... So as the movie gets goin pretty good she lifts the arm rest up and ask me can she lay on my lap because her back hurts so I say yes. She lays on me and puts my arm on her side and she holds my hand the whole movie, and I just feel so warm and lucky. And the movie we went to go see was Australia so it was kind of a love story. And when Hugh kissed the girl on the movie we held hands harder. And at the end of the movie we stayed in there a little while after it ended and we kissed, to me and my 18 years of life it was so romantic and I fell for her. So after the movie I asked her what kind of food does she want to eat and she says WHATEVER U WANT AND GODDAMNIT THATS ALL I NEEDED TO HEAR. So we went to a Burger place and she finished her burger before I did because we raced, So I just felt like this was something that would last because she was so beautiful and wasnt afraid to eat what I wanted to eat u kno. So we walked around one more time at the boardwalk and then kissed under the moon and it felt so right. CHECK THIS **** OUT the next day I ask her would u want to go with me(meaning do u want a relationship with me) and she says I WENT SOMEWHERE WITH U YESTERDAY...........and that hurt me because I thought we had such a great time together. Then her true colors come out she was just using me to get over her ex of 2 YEARS.....YEAH 2 DAMN YEARS. Then she had the nerve to say I was rushing her, at the date u where the one putting out all of the signs I just responded to them. She made me feel so low and I cried over her because I thought I did everything right. She told me I wasnt good enough and that she would not love anyone while she still loved of ex of 2 DAMN YEARS. It happened about a month ago but it still bothers me because she was so happy that night with me or maybe she was happy because she knew she was gonna be catered to. I really dont know what to think because I was told she would come when you least expect her and she came and left me looking confused. And till this day she thinks she did nothing wrong.????
