I really dont know anymore( please help 3rd time posting)?

Ok so heres my life...... i meet this girl about 8 months ago she was having trouble with her bf so i was there for her. we talked everyday and i thought i was making my way into her life, until well her bf went back to her and she accepted him....yea i know it broke me. but i mean im kinda glad he came back......kinda cause she was with him for 2 years and to lose someone after two years is kinda hard to take and i would never want that for her. so now shes back with him and i accept it........well i think i did. i meet him couple times and we say whats up to each other in school, but thats it. now heres my problem I STILL LOVE HER!!!! when she calls or txt me i pick up or txt back right away. sometimes i look at myself and ask what the hell are you doing. my friend told me that you still kinda have to love her but its friendship love. but idk. i know that if he breaks up with her tmw i will be at her door the same second, but i know that will never happened cause shes been with him for 2 years so that never going to happened. even when theres this other girl im trying to get with she is from the same country( Colombia) i think about her. so i need some advice from people that been through this or are going through this right now. thank you in advance.
