Living with a person who lies about every small detail of his life can be extremely stressful for anybody. Whether the person is your spouse, parent, or sibling, once you realize about their lying habits and that they have not been truthful to you, the relationship can never be the same again.
A compulsive liar is someone who does not have any motive for lying, he does this only for effect and out of habit. His first instinct and response to any query is to lie. Researches show that habitual liars (as they are referred to) have very low self-esteem, and thus, make up false stories about themselves to appear important and superior.
Sometimes, habitual lying is a result of a mental disorder that a person could be suffering from. People with mental illnesses such as Bipolar Disorder, Attention Deficit Hyperactivity Disorder (ADHD), Narcissistic Personality Disorder and Borderline Personality Disorder, often resort to lying compulsively.
Usually, a compulsive liar is very subtle when he lies, it is therefore not always possible to recognize that he is a compulsive liar. However, with prolonged and regular interaction, it becomes possible to recognize certain traits in them.
Denying the fact that they lie, coming up with more lies in order to cover up their previous ones, enjoying the reactions they garner from their lies, trying very hard to impress others, often forgetting their own false stories, and coming up with different versions of the same story--these are all signs of compulsive lying.
Methods of Dealing
Psychotherapy and counseling is identified as an effective treatment for people who suffer from compulsive lying disorder. However, because people with this disorder live in denial and do not recognize the fact that they lie, it is up to the people close to them to convince them that they have a problem which needs to be addressed immediately.
It will take a lot of effort and convincing power on your behalf to have them accept that they have a problem. Sometimes, telling the person that they will lose all their close ones if they continue lying might help in making them realize that they should start with the treatment.
Before the treatment, a few tests such as the NARCO might be run to determine the person's state. A psychiatrist will also examine the person for any kind of mental disorders. The treatment is usually a combination of psychotherapy, counseling, and medication, including role-plays, practical assignments, and counseling.
Dealing with a person who lies compulsively is stressful. But one needs to be caring and supportive of the person. However, if the person refuses to undertake treatment or even accept that he has a problem, then despite repeated attempts by friends and family, you should stay away from the situation.
