A healthy relationship brings into your life peace of mind and joy. A unhealthy relationship brings anguish and prolonged mental stress. How to know if your relationships healthy or unhealthy is by asking yourself these questions. During an argument do you experience yelling and physical violence? Are the people in your life controlling, judgemental and manipulating? Are your relationships of trust, honesty, support, good communication and mutual respect? Are your arguments with others settled fairly? Can you say you are maintaining a good relationship with family, friends, children and others?
