I think that for those of us that are Baby Boomers there is that model of Leave it to Beaver deep in our subconscious, creating more of a desire to fit that idea of a family unit that later generations weren't force fed. There are also some social circles which are all couples and don't welcome singles, particularly single women. This is all old thinking but it may be driving it.
Supply and demand may also be in play as we age - women outnumber men in the later stages of life.
The bottom line IMO is that some people need another with them, or think they do, to function in many settings. Strangely, those that feel that way seem to often want the more solitary people to follow suit.
Maybe they just don't understand.
Nail on the head, couples do not want to socialize with single women. And women do outnumber men, more as we all get older.
