After breaking up, my boyfriend said something insulting to me. How should I reply to him?

Since you choose to break up with him, there is no need to talk to him! He can only expose his narrowness and ignorance, which shows that your choice today is correct! But if you see his bad words, you must feel bad in your heart. You are regretting associating with him! Don't do anything that you will regret. I hope my meeting can help you!
