Me, Not Her

I'm not sure if you know it or not but I really do love you a lot you still hold a special place in my heart and you did right from the start But when she came along and took your breath away I was devastated and didn't know what to say I spend my nights crying time after time I spent my days lying saying I was fine Little did you know my heart was crushed inside and on that day a little of me died but with her you look so in love cause you are an angel from above I now have to teach my heart to move on for you are now forever gone But one thing I am unsure why cant it be me, and not her
