Maintaining the relationship?
What's the point of graduating from college if you still have to put effort into developing your skills?
At the very least it's an interesting cultural phenomenon if 'dates' are transmuting from something people are supposed to do before they get married, in order to get married, into something they're supposed do after marriage.
Clearly 'date night' is more important to people than I knew. Partly for this reason, I doubt it will be sufficient to save or maintain marriage, the institution, beyond a generation or two. It reminds me of the concept of quality time which was introduced in the 70s/80s at the same time as divorce was skyrocketing and children were being increasingly neglected. Yet who can gainsay it? Who doesn't want more 'quality time'?
It's very sad and I'm sorry to have brought it up.
