Why is it difficult to accept that most of us lead Double lives?

Why is it so difficult for us to accept that most of us lead double lives? Psychologists claim that a large number of people are living in 2 separate worlds, captured in their own dreams, fantasy, lies, shame and guilt that eventually power them into behavior which is way too different from their daily lifestyle. Having a secret life is not as unusual or abnormal as you may think.

A vast majority of people will live a double life at some point or the other.  Increasingly,  seemingly ordinary men and women sometimes hide extraordinary secrets from those closest to them: their families, friends and co-workers.

The question is what happens when this behavior takes over, damaging careers, breaking families and, sometimes, ruining the lives of many people?
It is when a person cannot include two inconsistent, reverse factors of a characteristic that we see aberrations and then all hell breaks loose.  So when we are not able to balance the two different lives we end up with having to lie to save one or other.  To some extent, duality can be found in most of our lives. We all have some special fantasies that are usually harmless, but only, until they become reality.
Fantasies are often personal and secret, and not hazardous. Everyone has fantasies, and usually they are lively, playful and forward-looking. You think about yourself in a different profession or imagine yourself as super popular athlete or super model or something like that. You would agree that its not unusual, for most regular, well-adjusted individuals to have a public self and a personal self, however some individuals get carried away when discovering the other part of their personality, developing a scenario that is risky and dangerous.
This can become  an obsession sometimes, excessive or unreasonable, and then is done without much respect or thought for the repercussions. Sometimes the risky dual lifestyle can also be a form of self-sabotage found in people who don’t feel they can successful or satisfied.
Sometimes when their duality unravels, and the person is captured and their secrets exposed, they could also be crying out for help. They simply don't know how to end the activities which have become problematic. It could be gambling or having numerous affairs or some other distressing habit and needs to be checked before it spins out of control.
As much as onlookers may feel it is a self determined action that really got the person into trouble, we also have to understand that the strange behavior is beyond their control. In the most shocking scenarios, these dual lives lead to criminal acts, violence and, sometimes, even murder.
Trying to understand why people lead double lives made me realize that often these people have been forced as children to live double lives.  In most case the man or woman learned very early on, to separate emotional pain, often of sadness and anger. Sometimes that meant hiding the truth from others, but frequently, it also meant, hiding the truth from themselves. A child who is treated with cruelty by his parents, for example, may well bury feelings of desperation and rage simply to get through each day. A child who is psychologically injured again and again, whether by loss or violence, may develop the ability to depart from reality, in order to protect himself from the full impact of those traumas.
It is these children, who when become adults,  retain the “ability” and inclination to slip the trappings of their own existences and write new life stories, almost without regard for their old lives. It is often the ones that couldn’t bear the truth, when they were most vulnerable, that remain comfortable or immune from it, at a great distance.
In almost ALL cases, the strategy never works. Pretending to be a different person may keep one’s demons at bay for months or years, but the underlying trouble in that individual’s soul will manifest itself, given time. You can’t outdistance the past. The truth wins every time.
Sociopaths are social predators who live their lives by exploiting others. When sociopaths live double lives, the prime reason is probably because it enables them to exploit multiple people, simultaneously. Another reason for double lives is perhaps, the promiscuity of sociopaths. Most sociopaths have a high appetite for sex, amazing stamina, and get bored easily and so seek new and exciting propositions faster. Often sociopaths simply love the game, of moving from one to the other in a kind of “duping delight.”
