What should I do if my ex teases me after breaking up?

Breaking up is to break up with your ex completely, and never have too much contact. People nowadays don't pay attention to these sections in life. So it has caused many tragedies in life, all of which are caused by themselves. Therefore, I advise you, when the current tease you, you must resolutely refuse, so that you can have the confidence to establish true love. Now that we have broken up, we should manage our future life well.
