Take it easy and let him take the initiative.
Ignore him ! As someone already said is about control not about missing you (he is acting like a user ).That doesn't mean he shouldn't miss you or feel bad about the break up which I'm sure he will eventually and if not who cares anyway .He isn't worth your time. You diserve and can do better .
Ignore it and move on.
whatever you want to do
Text that fool back and see if you can't forgive him. But if you ever see him look at another girl again destroy his BALLS! Literally
if you text him write him see him he will think you still want to be with him. if you truly dont then just let it be and move on. Love is something that dont just happen once, this is my opinion Hare Krishna
