What is the likelihood of a marriage lasting if the couple didn't live together while dating?

Much higher than when they do, most of the couples I know have been married over 20 some 30. Those that live together don't ever seem to make it to 20 unless they are not really fulfilling their marriage vows and gone from the home most times. The living together phase started in the last 50s, early 60s as it progressed in acceptance the divorce rate started to rise. Which is not good for any stable society. Society built on family units of father, mother and children is a firm foundation. Divorce, single parent with Disneyland daddies, one or both parents wandering off to let the grandparents raise the children and other groups of people just hanging out with each other doesn't make for any stability. Society crumbles when the family unit no longer functions as the majority.

Those who live together before marriage have a higher divorce rate. Fact.

life is full of mysteries and needs and wants and compatability and chemistry and understanding and moods and devotion and love and affection , the list goes on , at the end of the day the key word is --- communication --- good luck
