I scolded my ex-boyfriend online, saying that he had a bad personality and cheated my feelings, and he would get what he deserved. Then I threatened to kill him.

Scolding him will only show that he has no dignity! Talk about the time when you love me, and then divide the time. You must be calm! No matter when, you have to improve your status, so you really want to scold him! But it will make him look down on you even more, thinking that you can't live well without him! So I want to say that breaking up will only make the future stronger and better!
