Most Helpful Guy
You just focus on not adding fuel to the fire. Don't criticize, don't react, just work on your own mind.
Who knows what he has going on? The most important thing is that YOU are feeling good. And nobody will believe any rumors about you, if you remain level headed and happy.

You get to see a person's true character when they feel hurt or things don't go their way. His reaction and behaviour after the breakup determines who he really is. Now you know his true mindset
You learn more about a person at the end of a relationship than you do during the entire time you were with them. So I'd just cut all means of contact with him. Change your phone number, and just be thankful he is not in your life any longer.
He's obviously not an emotionally mature person. Anyone who knows you, will know his lies are totally unfounded. Most people will feel disrespect for him , and have a low opinion of him for being so immature and callous. He's obviously a vindictive person, and not worthy of your emotions. Take away his control by moving on from him
