It does "just click". I agree meaningful relationships does take work, but it's much more natural than "quitting your job so you can WORK on courting your future-partner FULL TIME".
Yeah, I think there's a healthy middle ground between "courting is inherently unhealthy" and "you should quit your job and court full time".
And it doesn’t even have to be conscious decisions either. In my case: I was working for two clients as a freelancer but mid projects it clicked with an exchange student who was about to head back to her home country in two weeks. But it really clicked, such that I neglected my ongoing projects in a really unprofessional manner. I didn’t want to, because I really needed the money, however I just slowly stopped working on the projects so I can spend as much time as possible with this exchange student. And when I wasn’t with her, I was losing sleep thinking of her, even writing songs for her - a prototype courting behavior. Needless to say, my unprofessional behavior came back to bite me years later when I was interviewing and the potential employer was checking references including my former clients. Was that all healthy middle ground? I don’t know. I just know that 10 years later, 5 of those married, and now with two children, I don’t really care :). I'm just as happy as one can be.
