When you’re in a situation where someone doesn’t like what you said or how you feel, your instinct may be to apologise.
This probably feels like the easiest way to resolve the issue and you might even tell yourself that next time you’ll be more careful about what you say around this person to avoid this outcome happening in the future.
In this type of situation, apologising is the wrong thing to do. You don’t need to apologise when someone disagrees with you. That says that you don’t believe you have a right to a different opinion. It’s also dismissive of your emotions which is unhealthy.
You have the right to acknowledge your own feelings and have them validated even if the other person doesn’t agree because your feelings shouldn’t be up for debate.
