I detest articles like this from both sides of the spectrum because they are slanted. IMHO, it is no one's business if someone wants to live together without marriage. Being married instead of living together first does not guarantee a happy marriage. You might just find out that you cannot stand to live together.
After what my son has gone through, I would recommend living together because in his case they would never have gotten married. It has been a total disaster. I was perfectly happy to have them living together as one of his friends said because it wouldn't last two months but her parents stepped in and they got married instead. Not working out but fortunately there are no kids.
It's no one's business until the live-in beats the crap out of a young child or worse yet, kills them. The news seems to be abundant with such stories in this day and age.
