A toxic relationship is a relationship characterized by behaviors on the part of the toxic partner that are emotionally and, not infrequently, physically damaging to their partner.
While a healthy relationship contributes to our self-esteem and emotional energy, a toxic relationship damages self-esteem and drains energy. A healthy relationship involves mutual caring, respect, and compassion, an interest in our partner's welfare and growth, an ability to share control and decision-making, in short, a shared desire for each other's happiness. A healthy relationship is a safe relationship, a relationship where we can be ourselves without fear, a place where we feel comfortable and secure.
A toxic relationship, on the other hand, is not a safe place. A toxic relationship is characterized by insecurity, self-centeredness, dominance, control. We risk our very being by staying in such a relationship. To say a toxic relationship is dysfunctional is, at best, an understatement.
Here are some of the more common types of dysfunctional behaviors that a toxic partner may use in a relationship with a significant other.
