My best friend Ditched me!?

ok...so me and my best friend have been friends since 5th grade. I am now a freshman in college. We didn't go to the same high school or anything but we were sooo close! in fact you couldnt even really say we were best friends, we were more like sisters! Well, the problem all started my sophmore year in highschool when i started dating the love of my life who im still with to this day. I usually ditched my best friend for him a lot and didnt think much of it. But she confronted me about it one day and I felt so bad and finally realized what I was doing and how I was hurting her feelings, which i never wanted to do and I broke down cried and apologized and stoped ditching her and ignoreing her and started to patch things up between us. This is where the problem starts, I understand what I did was wrong but I was truly sorry about it and really tried to do the right thing and start over. She said she forgave me and I thought everything was going to be back to the way it was. Oh was I wrong... After that day she started ditching me little by little... to the point where we only hung out maybe once a week. She started to get new friends that were really into the whole party and drinking scene which i totally am not into, and neither was she...well at least thats what she used to say. and get this the "new friends" she hangs out with are girls that used to make fun of her! anyways like i said i would only hang out with her once a week, yeah well this once a week deal was when she asked me if i wanted to go to target or wallmart with her and when i get there i realize that she only brought me along because she didnt want to go shopping for a new shirt by herself for a party that she was going to that night. I hadnt said anything for a while but senior year in highschool came and enough was enough! One week she told me to meet her at her house and we could hang out, i said ok and that i had to talk to her about something important anyway, i was going to bring up how i felt. I get to her house and call her on her cell phone...no answer, im standing on her lawn...she doesnt come out...i ring her doorbell...NOTHING...I finally text her and tell her to come outside and her reply is that "I cant im inside with my friend and were working on homework" At this moment I became FURIOUS and left! I started to text her and let her know how i felt and all i got in return were "hahaha's" and "whatevers" It was amazing how she didnt care at all! We stopped talking after that for the entire senior year. When the summer came I knew I was going away for college and I didn't want to leave without saying goodbye to her because even though we hadnt talked it just hit me that I was going away and she did mean something to me...she was my best friend...well i called her up and asked her if we could meet. she agreed and i went there and we talked about how we were dum and we shouldnt have faught...well when i went away for college we still did fight we faught because she wouldnt ever pick up my phone calls or call me back and when she did it was only to tell me about an awsome party she went to orr how she got totally wasted or something like that...i even got a myspace and wanted to try and keep in touch with her like that and added her as a friend but she would never comment me back at all or message me! bickering back and forth went on and on and i tried to tell her how She hurt me and how i wanted to make things right but it all went in one ear and out the other because apparently she didnt care...she pretended she did but i kno now she didnt. we said when i come back home for xmas break things would be different but she only saw me once for about 2 hours. then would only contact me when it was convinient for her and if i didnt call her she would ask "are you mad at me yes or no, i would usually reply idk its not like we ever talk anyways" and she would say whatever i m trying to make things right...WHAT!?!?!?!?!?! ugh i dono i mean i've been hurt by her so badly! she even lied to me about graduating high school...which she didnt! I am the one person who would never laugh or make fun of her about it and she lied! she kept trying to make her life seem sooo perfect just to make me feel bad about how much i miss our friendship. I dont know what to do i mean This girl used to be my second half! and now....i cant trust her, barely talk to her, never see her....SHES A TOTALLY DIFFERENT PERSON! UGH! i try and get over her and get new friends but noone ever compares to the friendship we had! and im afraid no one will! its just sooo sad.....i dont know what to do!!!!!!!
