REACHING OUT TO YOUR EX IS NOT WORTH IT
I seriously tell you that if you do YOU WILL REGRET IT. Do anything you can but DON'T REACH OUT TO THEM. Honest to god, on everything I love you WILL NOT feel better, whatever they'll say WON'T MAKE YOU FEEL BETTER, ONLY WORSE.
Just assume the worst. Assume that every awful thing that you imagined is true. Every last bit of hope you still have WILL DESTROY YOU.
DESTROY ALL THE HOPE OF MAKING THINGS UP WITH THEM BEFORE IT DESTROYS YOU.
