Shacking Up

It seems that in this day and age, more and more couples choose to live together before they're married. Me and most people I know were raised not to but the reality is that most people I know have or do. If you were raised one way but have since changed your outlook on "shacking up" (as our parents and grandparents called it), what made you change your views?

Do you feel it has lost the stigma and disapproval that was once attached to it? Is it important to learn whether or not you can live with someone before taking those vows? Are there any young people who see shacking up as something inappropriate? And then there's also the study that showed couples who choose cohabitation are more likely to end up in divorce.  What do you believe?
