You pine over the loss of some guy or gal in your life. You cry. You dream about them returning. You ache in the pain of the breakup and go over each and every detail of how it might’ve gone differently and you beat yourself up for your part in it…

Then one day, you run into this person that hurt you so badly and that you miss so terribly and you wonder what you ever saw in him or her?
Never fails. Can you relate?
