I would go completely dark on him. If he wants contact then let HIM contact YOU. Quit emailing him. Be short if he calls, act like you've got other things to do and he's interrupting you. Then get out and get a life. You're way too attached to him and it's hurting you, your PMA and your chances of reconciling. Detach. Leave him alone. Don't answer right away if he texts. Don't pick up every time he calls. Give him all the time and space he wants.
