NC why did she do this?

Hi, I just got out of a 2 1/2 year relationship. We started dating in high school, and now I'm a junior at KU. In the beginning about the first year and 1/2 everything was going good, the only thing that was bad was that we were a mixed couple, she is white, and I'm black, and her grandparents didnt except that at all. The past year she said was bad and we argued a lot, it got to the point where we would argue everyday, but it would be over stupid stuff, or her accusing me of cheating, and I never went to clubs or parties, or anything without her! Then she said I never wanted to see her, and I treated her badly, but I saw her more than my own mother! If I ever wanted to spend time with my family she would get mad! Our last fight she was mad that I volunteered to babysit my little cousin, and I couldn't really talk to her on the phone, she was MAD! We would see each other everyday in the beginning, then I went to a different college, but I drove back and saw her almost 5 out of the 7 days of the week in the beginning, then I saw her on thurs, fri, sat, and sun! But she says I didn't want to see her. We have been apart for about 2 weeks now, and after 3 days she was already seeing someone esle! I have treated this girl the best I could! My family has taken her to Disney World TWICE, I have taken her to almost ever great resturant in town, and given her diamond rings, and a diamond necklace she took from me the day before she broke up with me! and wont give it back! During our last part of the year, my parents got a divorce, I haven't seen my dad in a year, and my mom already got remarried after months and is not pregnant! I was going through some stuff! but even though, I would never curse at her, never hit her, and would always see her when I could, on top of being a full time student, and having a job, and paying for my own college, and buying my own car! It was hard, but I tried my best! What did I do to deserve this! She says she really likes this guy, and he treats her nice, but I thought I did, but she says that I didn't in the end! I did the best I could, she would never give me time to myself and now I get hit for it! Then she says she wants to drink, when she never did before, and she wants to do 21 year old stuff, so I say can't you wait until I turn 21 in 6 months, she says thats too long. I keep asking her how I treated her wrong, and she just keeps saying we arugued and fought to much, but she was the one starting almost all the arguements! Now shes just like I don't have any feelings for you, only as a friend, but the day before she broke up with me, we laid in bed together naked, and she offered me sex, but I didn't want to because toward the end of the relationship I wanted to practice abstinence, and she agreed because she would always be afraid when she was late. That morning she wakes up gives me a kiss, and we wish each other a great day, and then that afternoon, she got mad at me about the babysitting thing. Now about this guy she met him at her 21 party, we had a huge fight over her not accepting my cousin because of he was a ladies man, and she felt he would infuence me, but thats no excuse to hate someone, he just wanted to come over and wish her a happy birthday, she never accepted him, and he did nothing to him, so I said I'm tired of you not accepting my family, and I am leaving, so she starts screaming and beating me, and I leave, and the cops come over and ask what was going on, I was already gone.. so later on that day I expected her to call apologizing about being so mean to my family and beating me, but she never did, and so later on that night I go over because I didn't want her party to be a total loss, and we have fun while I'm there, and I saw him there, and I could tell he was looking at her. I guess before I came over he was talking to her, but how could she leave me after all the good times, and how much I sacraficed for her! I quit jobs because of her, she didn't even want me sitting at my mothers table at her wedding because she couldn't sit up there! Why is she doing this to me! Whenever I wanted to leave her, because she would curse at me all the time, or hit me all the time, or threaten to run off the road in her car with me in it, I gave her another chance, why can't I get one?
