He just wants you to feed his ego and become another one of his sluts and followers. This is how he gets his power and you take it away by ignoring him. Like a pendulum if you react you give him more power to his swing.
The best approach is to consider you had a lucky escape and put it down to experience and lessons learnt. Don't have anything to do with people who think they are better than you are. Ignore him because you are better and now you know it. Ignoring him takes away his power.
Only allow nice people to have your time and this guy will NEVER be nice.

HI, first of all, Im really sorry about what you're going through.
It seems as though your ex just wasn't the right person for you. He seems very immature, and frankly, you deserve someone better. You can't control his actions, but you can control how you respond to them. Don't be mad, or angry, or yell. Be mature, avoid him when necessary and just be the bigger person. But if the problem gets out of hand, I would suggest telling a friend, parent or someone you trust to confide in. After all, they will be there through all the heartbreaks. Just know that you are better than him, and that you have the power right now; don't give it back to him by entertaining his childish actions
good luck :) I hope everything turns out well
