i don't know what road we're on 
i don't know what we're heading towards 
but i know my heart is all yours 
all my friends tell me i'd be better off on my own 
and sometimes i believe em 
but i know i can never leave him 
mixed signals mixed signals 
they're killing me 
i don't know what you are 
but i know what i need 
the goodbyes the hellos the i need you's 
the no i don't every time i start to close the door 
you knock and i let you in 
loving you is my greatest sin 
you tell me to get lost and that your done 
i see it in your eyes you wanna run 
but i know you know that i'm the only one 
i can find someone who'd never make me cry 
someone who'd never tell me goodbye 
but i know that i would never survive 
mixed signals mixed signals 
they're killing me 
i don't know what you aren't 
but i know what i need 
the goodbyes the hellos the i need you's 
the no i don't every time i start to close the door 
you knock and i let you in 
loving you is my greatest sin 
i don't know why i love you 
i don't know why i stay 
i don't know if its worth the pain 
but even when you slam the door and drive away 
i still set the table for two 
babe you know i'm waiting on you 
to buy me a bouquet tell we're okay 
and that you so so sorry 
and i believe you every time 
but i can't lie these 
mixed signals mixed signals 
they're killing me 
i don't know what you are 
but i know what i need 
the goodbyes the hellos the i need you's 
the no i don't every time i start to close the door 
you knock and i let you in 
loving you is my greatest sin 
loving you is my greatest sin 
loving you is my greatest sin
