No, but I can tell you from personal experience that it leads to many dramatic problems couples can avoid if they wait until they're married to live together. It also devalues the marriage which becomes simply something that happens throughout your history of living together rather than the start of your life together. Many relationships where couples live together before marriage end prematurely. This happens in marriage too, but at least married couples get that far.
Please elaborate on your points, because right now, it doesn't make that much sense.
You'll find that a common theme in bbag's postings. He's like 20 something (or less) and knows it all, you see.
Oh, and welcome.
