Also, I'd literally never heard the term "millennial pause" until reading this thread. I looked it up, and then checked my videos. It turns out that I very much have it. I guess that settles which generation I am.
Incidentally, here's something that kind of relates to this. On certain dating apps I've noticed that some people have a bizarre and very specific age range preference. Not a round number (which is silly enough in itself IMO) but, for example, someone who is 33 might have 31-34 as their age range. Does that mean someone who is going to turn 35 next week will then be out of the question, and does a 30 year-old whose birthday isn't until next week need to wait until then to message this person? Plenty of people are 'younger' or 'older', by a little bit or by a significant amount, in terms of their personality, looks, health etc. In adulthood, those factors and others are more important, surely, in determining whether a relationship or friendship will work.
I don't think it's that weird, I think most people would want a partner to be +/- 3 years of their own age.
I've always felt like age gaps seem more reasonable if the guy is slightly older. Like, a 26 year old guy might want a girl from 20-29 (-6 to +3), while a 26 year old girl might want a guy from 23 to 32 (-3 to +6). At least it often tends to be that way for whatever reason.
