Nope--living together before marriage does NOT equal promiscuity, as the dictionary will prove. Living together is a choice we can make to get to know someone better. It doesn't work for everyone, but it does work very well for many others (as evidenced by the those who have posted their stories)--including myself.
I married as a witness and therefore didn't have the "option" of living with him beforehand. If I had, I'd have realized that he was gay. We were married for 8 years and did finally divorce. Fortunately, we still have a great relationship after divorce and I know that I needed to be married to him to get out of the borg. There aren't too many who can be THAT patient with me....
In my opinion (for ME), living together gives you the day in and day out 24/7 view of the other person (similar to having children vs. babysitting children). And although you CAN get to know someone very well through visits, calls, letters, emails etc.; there are some things you NEVER know unless you live with them. And if the other person has habits etc. that you simply cannot tolerate, you're up sh** creek if you're married when you figure that out.
Don't get me wrong--I realize that there are others whose past experiences or current belief system does not allow them to feel comfortable with living with someone before marriage. Thankfully, it sounds like most of us realize and respect the differing viewpoints and situations of others. I only know what worked and what didn't for ME--and I love sharing my experience as well as reading others'.
