A toxic relationship is one that is harmful. While some signs of a toxic relationship are more obvious—like physical abuse, repeated infidelity, and inappropriate sexual behavior—others can be harder to detect. It may involve disrespectful, dishonest, or controlling behavior.1<br /><br />For example, your partner cuts you down frequently. As a result, your mental health may begin to suffer.<br /><br />Whether you are single or in a relationship, leaving a potentially toxic relationship is not easy. It first takes the realization to know that you're in a toxic relationship, and then it takes accepting that the relationship is toxic. Once you have confirmed the signs of a toxic relationship, leaving takes social support, courage, and also self-validation knowing that you will find someone better. <br /><br />Source: Psych2Go
