twisted every way

Theres a song in my head and i can't go where its led me to.
It sings of you and me and of our destiny
but I can't see myself with you.
but Theres a voice in the dark, how it sings to my heart
and pulls me away from you.
...How it sadens me to say, that I miss it everyday,
and no matter what I do, it will never come from you.
And how can I tell you, nkowing that it will kill you,
But I can't stay with you cause I do not love you.
I don't know what to do.
