i dont think it's like that. i think it's more about an ex that really loved this girl and she didn't feel the same way back then, but once she saw him with another girl it made her want him back (jealousy maybe?). that's happened to me, i think its like a sense of rejection its like when someone who loved you strongly gets over you and moves on, even if you dont really care about them you still feel rejected.
