Is your husband or wife, boyfriend or girlfriend a compulsive/pathological liar or a sociopath?
To begin with, it may help to understand the difference between a pathological or compulsive liar and a sociopath (see types of liars).
Ultimately, making this type of distinction may not be that useful. Because in either case, the outcome is typically the same: dealing with a compulsive or pathological liar is very difficult to do. And unfortunately, sociopaths cannot be changed (seelovefraud).
A compulsive liar will resort to telling lies, regardless of the situation. Again, everyone lies from time to time (see when lovers lie), but for a compulsive liar, telling lies is routine. It becomes a habit—a way of life.
Simply put, for a compulsive liar, lying becomes second nature.
Not only do compulsive liars bend the truth about issues large and small, they take comfort in it. Lying feels right to a compulsive liar. Telling the truth, on the other hand, is difficult and uncomfortable.
