I dunno. I'm trying to think of a way to encourage you to stop picking your open wounds, and I'm coming up short. The only person that can make this problem go away is YOU. No one can rescue you, no one can say the magic words that will suddenly infuse you with the strength to write off this guy for good.
I think if you knew the perverse pleasure he took in stringing you along, you'd run away as fast as your legs would carry you. You think he cries after he gets off the phone with you? You think he counts the minutes until he can talk to you again? Hell no. You don't ever cross his mind until he decides he needs some entertainment and mastubatory self-validation.
Changing to an unlisted number and a new email address is The. Best. Thing. You. Can. Do.
Aren't you tired of the pain yet? We're all rooting for you, don't let us down
