Couples who sleep together stay together. This morning I read an article that was titled "the case for separate beds." Here is my view and advice on that one. Get the smallest bed you can. If the two of you can sleep in a twin size bed than try and do it. In a recent survey couples admitted that as they moved forward together in life and their beds got bigger, their lives became more separate. Once they began sleeping in separate beds the marriage was pretty much over. They had a business relationship and not much more. It was just too expensive to get divorced or they wanted to stay together for the family, whatever the reason was, it was a sexless marriage.
Sex should never be the only part of your relationship, but it is important and so is staying in love. Of course there are times when you have to sleep separately, business trips, or one of you is sick, or up with a new baby, that makes sense, but be careful because if it becomes a lifestyle, you might be headed down a lonely road.
