She's my ex. I can't cross her from my memory
  She meant everything to me she meant every word she said
  When she said, "I'll never love again. Be my ex until the end."
  And I know I'll never feel that way again
  She's just my ex
  She's my ex. She marks the spot where I'm the weakest one
  I can't expect she'll change her ways; can't accept the things she's done
  She's just my ex. Nothing more nothing less but she'll always be my ex
  She's my ex. Don't cross her path she still belongs to me
  She'll be my ex till I say when till I get her back again
  'Cause I know I'll never love again. Never need another friend
  And I know I'll never feel this way again
  She's my ex. She'll cross my mind a thousand times today
  Still have a million things to say, guess I'm better off this way
  Cause I know she'll never love again. She
    'll be my ex until the end
  And I know I'll never feel this way again
  She's just my ex. Nothing more nothing less but she's still my ex
  And I could never kiss that face goodbye
  But I could never stop to wonder why
  She looks so pretty, she looks so pretty
  And I know I'll never feel this way again
  She's just my ex
