Harmless Joke

What am i doing
why do i try
not wanting to continue
because of this lie

leading me on
with out a cause
started as a harmless joke
between me and some guys

but you took it farther
and then did i
but now my hearts broke
and I'm wishing i could die

why couldn't i leave it alone
why did i let it get this far
now my heart is bruised
and i don't know what to do...
