So you and your boyfriend get in a little disagreement, Right? And you two break up. And then he goes and find a girlfriend the next week, and get THIS.... She Looks almost EXACTLY LIKE YOU!!!!
How does it feel when you face the reality that guy wasn't actually attracted to your personality, but just your good looks. And so he found himself "your doppelganger" that probably has an even better personality than you?
Update:Doppelganger as in Person that looks like you in every way, but is completely Unrelated to you, Maybe Even from a different country as you.
He was seeing her, well before the break up.
