Her ghost is there   I can see the outline of her shadow traced in the air   Sometimes I see her bended over your shoulder   I think what lies has she told you   And I see a smile light up your face   You like what she says   And I wanna cry, it's killin' me   But I play dumb instead      She's the uninvited guest who lives in our house   She's the other woman who's on your mind   Who's in your life?   I'd have to be blind not to see it, not to feel it   And I'm runnin' second best   To the uninvited guest and it's breakin' my heart      You don't know how I know   If it all was in the open, you'd deny that it's so   Just like the old song torn between two lovers   It's that happening to others   It's happening to you and me and the pain is intense   I should leave you but I love you though   It doesn't make sense      She's the uninvited guest who lives in our house   She's the other woman who's on your mind   Who's in your life?   I'd have to be blind not to feel it, not to see it   And I'm runnin' second best   To the uninvited guest and it's breakin' my heart      I should leave you but I love you though   It doesn't make sense      She's the uninvited guest who lives in our house   She's the other woman who's on your mind   Who's in your life?   I'd have to be blind not to see it, not to feel it   And I'm runnin' second best   To the uninvited guest and it's breakin' my heart   It's breaking my heart
