It ain't like there's a lipstick stain No you ain't that cliche But even so One 1 a.m. and your phone lights up You don't say a word about who it was And I let it go I feel you changing There's little signs What you're not saying Won't change my mind I don't wanna know I don't wanna hear it Doesn't matter where you go Behind closed doors If you're happy If you love her more As long as you come home I don't wanna know Walk in the door after working late I'm wearing that dress from our first date And you don't notice But even when you're here you're somewhere else You can't see it, and I'm in hell 'Cause I don't show it If you call her baby When you're alone This might sound crazy But I don't wanna know I don't wanna know I don't wanna hear it Doesn't matter where you go Behind closed doors If you're happy If you love her more As long as you come home I don't wanna know If you'd rather be beside her If you'd rather give her your last name I don't wanna have to wonder All the same You're still the man that I'll always love Even if for you I'm not enough I don't wanna know Behind closed doors If you're happy If you love her more As long as you come home I don't wanna know As long as you come home I don't wanna know
