Rihanna - Unfaithful

And I know that he knows I'm unfaithful

and it kills him inside

To know that I am happy with some other guy

I can see him dying

I don't want to do this anymore

I don't want to be the reason why

Everytime I walk out the door

I see him die a little more inside

I don't want to hurt him anymore

I don't want to take away his life

I don't want to be… a murderer
