In a world full of 7 billion people you're going to waste your life crying and tearing yourself apart over a *******. Poor you! There are good memories, you won't forget this person but if they had the audacity to disrespect you then you have to accept the fact that this person was fake, they either got what they wanted from you and left or never got what they wanted and left because they had no intention to stay anyway. Don't live in the delusion they promised you.
