i am sorry to say, but once you break a girl's heart you leave room for another to come mend it. now i am not saying that she's off with another guy, but i think you pretty much ruined your chances of getting back with her, long distance relationship or not, when a girls hurt, especially by lying it's hard for them to believe anything that a guy says to them afterwards. if you really loved her, you would have treated her better while you were still together, wouldnt' you agree? just move on and try to do better in your next relationship. good luck to you.
