respectfully i can only speak for myself, i hope that my children never think of their lives as a lie, that they realize their parents are and were not perfect, are human and did and do make the choices that they believe are the best at the time. Personally i've had friends whose parents divorced and they are sure things would have been better if they'd stuck it out, and ones who wished that mom and dad had called it quits, it is impossible to step into anyone else's shoes. i balance each and every decision i make as i'm sure others do in their circumstances. So i never expect to have to explain to my kids anything about their lives not being anything but real, with the ups and downs, foibles and follies and all else that life entails. So something to think about for me each day is that i love my kids beyond words (and they know it!)...their life is real, their mom is human and the good bad and ugly, she works to give them the best life, not the perfect life, the best...they may or may not agree or disagree with the choices made, but there will never be a moment they can doubt that it was made with the best intentions
