 Didn't know I was lyin'
 When you said that I didn't mind take it sometimes
 Silver without a linin'
 Guess you must be gold
 Didn't know you were hidin'
 Someone that was textin' you when you're alone
 So, baby, why you cryin'
 When you did me cold?
 You say you miss me when he's unavailable
 'Cause you think I'll always be there
 We both know love can be unpredictable
 So I'll make it clear
 Better figure it out
 'Cause I ain't no backup man
 I ain't no backup plan
 I ain't no backup man
 Better figure it out
 'Cause I ain't no backup man
 I ain't no backup plan
 I ain't no backup man
 I know you've been with him lately
 And he's tellin' you everythin' you wanna hear
 Got your head in a haze-y
 Wants to make me disappear
 What we have is amazin'
 So why you wanna put it in the rearview mirror?
 What pictures he paintin'?
 I'll paint your head
 You say you miss me when he's unavailable
 'Cause you think I'll always be there
 We both know love can be unpredictable
 So I'll make it clear
 Better figure it out
 'Cause I ain't no backup man
 I ain't no backup plan
 I ain't no backup man
 Better figure it out
 'Cause I ain't no backup man
 I ain't no backup plan
 I ain't no backup man
 Better figure it out
 'Cause I ain't no backup man
 I ain't no backup plan
 I ain't no backup man
 Better figure it out
 'Cause I ain't no backup man
 I ain't no backup plan
 I ain't no backup man
 'Cause I ain't no backup man
 I ain't no backup plan
 'Cause I ain't no backup man
