Develop your own interests, hobbies, and goals. People in a toxic relationship often feel that they can’t be who they are, and may rely on the other person to fulfill certain needs. The best way to overcome that is to learn how to fulfill your own needs by focusing on what makes you happy. You’ll also improve your self-esteem, which will help you break the toxic cycle. Working on yourself will help you be a better, more stable partner. Even if the other person doesn’t change, your relationship will still improve. For example, you might enroll in a class, join a recreational sports team, or try out a new hobby that interests you.
