Hated and loved at the same time?

I'm a university student, met my girlfriend in a foreign country, we fell in love after knew each other for 1 month. From the verystart, we all knew that this relationship could be a risky one cuz we wouldn't be studying in the same city when we go back home.We had a great time together generally, even though fought almost everyday, mostly because i'm more of a open and outgoing kinda guy and she's not,she's shy sensative and had a lot of experiences of being with a guy(tons of them, oh god help me!) ,and even when she first agreed to be with me, she still thought of her ex very much and compared me with those guys.sometimes i got mad and yelled at her cuz i saw her as my one and only.But there are many happy moments, we celebrated our anniversary monthly and more when there were holidays. Days went by just like this for 6 months, then one day she said she couldn't take it anymore cuz i couldn't give her what she wanted, that she's always upset and sad because of me and seldom was happy.So we broke up. Even though we still love each other, we really do. She said we were not sofisticated and mature enough to be involved in a serious relationship. Unless we both grow up, we can't be together happily and we can't be together.After that i felt like we were in a cold war. She has been afraid to see me ever since and i always felt nervous about every little thing i say and do.I tried a few times to persuade and we were almost back together, but always ended up in tears somehow.Are we afraid of conmitment or our history was something really hurting? i was told that up till now, she still can't sleep well everyday and thinks of me and us being together, even in her dreams she did so.Sometimes late in the night she picks up the phone and just bites her lips not to call me. She writes in her diary that she wants to get back together so much but never has her felt that way about anyone.She loves and hates me at the same time.Now i hate myself for not being great enough for her and feel like i can't survive for even 1 day without her.Is like wasting all my life just thinking of her. What should i do? What can i do? don't wanna let go but she won't agree for a 2nd chance.i'm in the middle of nowhere,somebody, anybody helps please!
