Girlfriend broke up with me I need help?

Me and this girl have known eachother since about freshman year of highschool (now going into senior) and we never hung out really just an occational talk on myspace or facebook, and recently I actually went to hang out with her and instantly it was like love at first sight, I fell in love with this girl and we were together ever since... until last night. I really loved this girl like no ones business, no one could explain how good I felt about her and how much I loved her. Everyday I would make the 24 minute drive to her house and again to get home just to be able to see her, I would take her out to eat and to the movies at least once a week, i've bought her clothes and such and we were so happy. She does get some anger build up sometimes like shes on her period but it isnt ever really that bad I always knew how to make her smile just after she would spark up. We were so close hanging out as much as possible, probably too much now that I look at it. But lately since it's summer I would pick her up and we would go to the falls near by or we would go to the beach or she would come here and we would hang out with friends, go to movies or dinner and just hang out at her house. Well lately it hasnt been exactally smooth, just little fights because I was getting upset that she almost completely stopped showing affection and she claimes as well as her parents claimed that she isnt very affectionate that I should be lucky to get attention out of her and I did. But yeah so she slowed it down to kissing me only a couple times a day and she got annoyed whenever I would touch her for some reason but everyone said it was part of her personality. So with the fights about her not being affectionate I took her home yesterday and after I got home she called me and told me we need to break up and started saying how we wont work because of college and I tried telling her no matter what happens we can make it work, you have to love and truely believe and she just wouldn't listen and said we wouldnt work, and then changed it to that I'm too awkward around people like I dont make eye contact, then she changed it to her "love meter" is at 0 for me now. I'm honestly so confused I tried talking to her today and she told me she cant handle a relationship, that she lied to me when she promised she would commit that it's just too hard for her and shes a kid she wants to live. I tried so hard to make this girl happy and still give her the time to spend with friends and doing whatever she wants but I'm so lost. Why yesterday morning did she claim to love me then not want anything to do with me with night time came around. Is she confused? What do I do? I'm honestly in love with this girl and I dont want to see myself without her :( Can anyone help me out here? Give me some advice?
