Gaslighting is a form of emotional manipulation that is meant to leave the victim feeling insecure and questioning their own reality. It is a common tool used by narcissistic and abusive spouses to control their partners. The term gaslighting comes from a 1938 play entitled Gas Light, in which a husband tries to make his wife think she is losing her mind by doing things to make her doubt her own senses and reality. Some signs that a spouse may be trying to gaslight their partner include blaming them for their behavior, saying proof does not matter, manipulating their partners perception of reality, and making them doubt their own senses and memory. Gaslighting can be subtle and may accompany other forms of domestic abuse, including verbal, emotional, financial, sexual, and physical abuse. Victims of gaslighting may experience anxiety, depression, hopelessness, or helplessness. If you suspect that you are being gaslit in your marriage, it is important to seek help and support from a trusted friend, family member, or professional.
