On that dance floor

I trusted you.
i let myself get attached.
i told you i didn't want to but you said i would regret it if i didn't .
you guessed wrong i regretted it because i let it happen.
you were so cute and funny and all i did was smile around you.
then that girl came around again and i lost all control.
you dumped me right there in that room.
on that dance floor where i watched you lie to my face and break my heart.
i let you get inside my head.
i let you get in there and screw everything up.
i had the best life until i let you get inside my head.
thanks a lot, but i don't need another person inside my head.
