How do I stop my LDR GF from breaking up with me?

i was in a LDR for 3 years and we have now lived together for 2 years so they do work and dont let anyone tell you any different. with the 'you wont fight for me thing' just sounds like mind games to me. would she rather you were a controlling freak who questioned her every move?? give her a little time to calm down and get over herself maybe, i dont think she realises how many girls would kill for a nice guy like you. maybe send some flowers to her work or school? (dont know how old she is) and just get them to write 'i love you' on the card. hope it helped :)
