Get my ex back

me and my gf were in a long distance relationship for 2 years and were really serious for each other.before that she was my best friend and then when i came abroad she told me she loves me and i accepted her she was loyal and very caring but i was quite busy in making my life in new country and was unable to give her time and care she used to beg me for that but later she gave me signs of non attractiveness and i became more of nice guy to her but suddenly she broke up with me after 3 months saying that she is no more attracted and she lost the love for me during the period of ignorance.when i said her i love her and care for her she said that i am being needy and told me that she will never come back even she wants to.she told me to be friends but i rejected coz it was not possible for me to see her as a friend any more.but i realized my mistake and want her back its not too long back just a month. is there any way to get her back coz her friends told me she is lost now days and just trying forget you but still love you and they say that she will come back to me when she will miss me. but how?? what can i do?
