Codependent relationships are characterized by a lack of healthy boundaries, the inability to make important decisions for oneself, and low self-esteem. Without healthy boundaries partners in a relationship tend to take advantage of one another. This can really strain the relationship and lead to its demise. Most partners in a codependent relationship try and do everything they can to please their partner while ignoring their own needs. One partner may even enable the other partner to engage in reckless, irresponsible, and destructive behavior. Studies have shown that codependent individuals were abused as children. Exercising healthy boundaries means standing up for oneself, asking for what is needed from your partner, and saying no to things that go against your principles. It's important to replace unhealthy codependency with healthy interdependence. People who are interdependent make sure that their needs and the needs of their partner, friend, co-worker, etc. are both met. People who are interdependent tend to have supportive and fulfilling relationships. Remember that it's never too late to seek the therapy you need to improve your life.
