It is often very hard to end a love relationship, even when you know it's bad for you. A bad relationship is not one that's just going through the inevitable periods of disagreement and disenchantment that occur when two separate people come together. Bad relationships are chronically lacking in what one or both partners need. Such relationships can destroy self-esteem and prevent those involved from moving on in their personal or professional lives.
Bad relationships are often fertile breeding grounds for loneliness, rage, and despair.
In bad relationships, the two partners are often on such different wavelengths that there is little common ground, little significant communication, and little enjoyment of each other. Remaining in a bad relationship not only causes continual stress but may even be physically harmful. An obvious harm is the physical abuse that is often a part of such relationships. In a less obvious way, the tensions and chemical changes caused by the constant stress can drain energy and lower resistance to physical illness. Continuing in such bad relationships can lead to unhealthy escapes like alcohol or drugs and can lead to suicide attempts.
