Boomerang effect

Before there was an us
there was a you and me
i didn't expect much
couldn't see what we would be

you quickly stole my heart
it was yours before i knew
and from that day on
i'd do anything to be with you

you broke my heart once or twice
three times to be exact
but even after all the pain
we both knew i would come back

you explored your options
i tried to explore mine too
but we just kept coming back
you to me and me to you
