Here's to second chances

I gave you a second chance
you told my you'd make things right
again you proved me wrong
now things end tonight
you said you were sorry
and that you made a mistake
but how much more hurt
do you think i can take
i gave you my trust
and let you back into my heart
but once again
you tore it apart
what were you thinking
what was going threw your mind
now im sitting here wondering
whats you excuse this time
everynight i would go to bed
with tears running down my face
wondering how i ended up
being your biggest mistake
so heres my good-bye
to what we've never had
how did something so good
turn out so bad?
