Why did you lie to me?

I think my heart is broken,
not sure who to blame,
deep down i know you're different,
compared to other boys you've never been the same,
you were sweet,
you said that you really did care,
but now thanks to you,
I cant stop these endless tears,
my heart feels like it's shattered,
broken in every way,
remember when you said 'I love you' every single day,
I cant believe that whole time was filled with lies,
and now that you left me for her,
I cant seem to say good bye,
How could you not see that i really did love you?
How could you not see that my feelings were true?
you took my trust, my heart, my mind,
you crushed and mixed them to for anger and jealousy combined,
If you really didn't love me,
why didn't you just speak out?
but for when you need me I'm here to be re-broken and tossed about.
