Emotional abuse is a form of violence that involves improper and unhealthy interactions between two or more people. It can be caused by factors like inferiority complexes, unresolved personal problems, and lack of ability to understand healthy relationships. Abusers tend to be emotionally immature and exert excessive control over victims, while victims have low self-esteem and seek crumbs of affection. Signs of abuse can be subtle messages or behaviors that manipulate or play mind games. Prevention requires awareness of key information and seeking help from others.
