I want you... but you want her

I loved you with all me heart,
but that's what tore us apart,
i gave you my trust,
which was only meant for the 2 of us
you fell in love with her instead
all these thoughts of you were stuck in my head,
i want you, but you wanted her,
here is my heart that i cannot mend,
what hurts me the most..
is that she is my best friend
