Me or her

I heard from a little bird to day,
you are getting married next year,
how can you marry that girl, and not feel one bit of sorrow,
for someday she will find out that you loved me,
and every time i see you you want me,
again,
and again,
it hurts to live this lie,
but the feeling i get when you are not part of my life,
is worst than words can explain,
you don't want to do this,
you are only going to hurt her,
but it is going to be worst than you ever thought,
you said to me one night,
you were stuck between
a rock
and a hard place,
you promised we would be together,
but that never happened,
all i can see in you now is a liar,
a cheater,
a bad person,
you took everything from me,
you were my everything,
even when i see you,
and think all of those horrible things,
i still go back time,
and again,
you have me by the heart,
i just wish you would let go,
i don't know why you are the only one i see,
but you are,
you have all the luck,
you have two girls that love you with no end,
but you still want more,
you cant have both of us so you need to chose,
me or her??
