When will the hurt stop? My ex said some nasty things to me, and with a smile on his face?

Well time heals all wounds, yours will end soon, just enjoy your life, be with friends and continue your search for mr. right. You know this guy was a loser so don't give him the pleasure of being in misery, continue to move forward and eventually you'll forget about this loser, and again the hurt will fade, again it just takes time.
