You can’t change someone who doesn’t see an issue in their actions.
You change for two reasons: Either you learn enough that you want to, or you’ve been hurt enough that you have to.
Actions speak louder than words. We can apologize over and over, but if our actions don’t change, the words become meaningless.
You can’t change how people treat you or what they say about you. All you can do is change how you react to it.
