Intentional ignorance would be a suitable definition. We live in a constant state of denial. Nobody's life is perfect, everyone has that one part of their lives that is hallow or fatally broken. The secret to a perfect life is acceptance, mixed with a little bit of denial. Denial helps to cover up the wounds and scars which you know cannot be healed anymore. It helps to lessen the burden which you know you will have to carry for the rest of your lives. Denial also helps us to overcome temporarily, feelings that could lead to severe heartbreaks. It helps you to ignore all the bad aspects of your life, and focus on the good ones.
Once in a while, we wake up, either when forced by people or circumstances. Or when it just gets to hard to overlook the reality which is right in front of our eyes. At that point of time, we feel like we have deceived ourselves all this while. We feel like there is a lot that we could have done, had we walked with reality. But this is just a momentary rush that you get, a depressing phase. Because there are certain things which you cannot fix. And denial is the only way to heal the pain, the only cure, the only aid, in most cases. Once in a while, all those self told convincing lies fade away, and the truth is clear and upright, as harsh as it was. This is when the bad times and the bad days begin to take over. You regret all that you've ever done. You call yourself weak, and a coward. You walk away from all those happy faces, because you don't deserve to be with them. You acquired your happiness and contentment by lying to yourself. But there's still hope. It is not long enough before the foggy layer of denial and lies rises, and you get that sense of relief, all over again. Denial is bliss, and for some, it is the only way out.
