Emotional abuse is one of the most insidious ways one person can cause harm to another human being. Through constant jibes directed at one’s self-esteem, even the most confident person can be broken down over time. Sometimes it is obvious, like name calling and threats. Other times, it involves comments that undermine, manipulate, and emotionally bruise. The following article points out some key behaviors that mark this kind of relationship. It can help clarify that otherwise might be elusive, confusing, or even hard to admit.

Should this be something you struggle with, please seek the support you need to reclaim self-respect and empowerment. I recommend the following book to help further clarify what you are going through:
