My grandparents (born in the 20s) had twin beds for most of their marriage (as far as I know). They adored each other, really affectionate towards each other until they died within 6 months of each other in their 90s.
Awwwww.
It's weird actually, how some people assume if a couple has separate beds or separate bedrooms that they're not close, not intimate, and there are very likely problems in the marriage. They can't comprehend how a married couple can possibly sleep apart. 
Yet, all the couples I have ever known who have long marriages (30+ years) have slept separately for the last 15-20 years or more. Most of them slept together for the first 10 years or so, as they thought it was romantic and so lovely to snuggle with hubby.
That novelty wears off quickly, when he starts snoring... 
And when an extra bedroom pops up (if a child leaves home, or you get a bigger house,) many women move into another bedroom. (And as I said, once you have your own bedroom, you will never go back!)
Also, some couples I have known over the last 20-30 years, who have always shared a bed, have split up.
So sleeping apart means naff-all. Indeed, I strongly believe that sleeping separately (ergo getting a good sleep, and having your own private space/more me-time in your own room) actually strengthens a marriage.
Just my opinion of course.
