That's a hard question. I myself have been known to lie, and its something I have to fight. Imagine if you as a child were constantly in trouble, wouldn't you lie to stop being in trouble? This is how it starts for some... And it never gets dealt with till they are older. Some become habitual, some become defensive liars. Its a hard thing to deal with. My love deals with my problems with patience and kindness. That being said, I have to be completely open or I could risk our entire marriage. I have been caught lying, and once we sat down and discusses the why of it, she understood and is working with me to be a more honest person. It all depends on the love and strength of the couple. And what each person is willing to deal with. For some my problem would have been a deal breaker. But luckily I found someone who understood the why, or loved me enough to try too, and work it out with me. I'm sure there are many different scenarios one could play out but in the end its a case by case, person by person type issue. The irony of my foible is that I can't stand to be lied too. Go figure that one out. =[
