Setting boundaries is important, even when the relationship is stable. Many believe that setting boundaries is something that is done after your partner has crossed some sort of line, but this isn’t true. Setting boundaries is all about expressing your personal beliefs and establishing your agency in the relationship.
Your partner cannot read your mind, so without boundaries, they will not be able to figure out what you require in order to aid your personal growth journey. A healthy relationship is one in which both partners communicate their boundaries and respect them to the best of their ability.
