Okay, but you didn't point out that shift from mostly newly dating or attempting to find a date to partners in an already established relationship.
In that context, you have a point. One would expect some give and take on many things in such a scenario. I don't know that the word 'standards' is the best choice there because it has a specific and different connotation on the dating market than it does inside a relationship. That may be semantics.
Regardless, the rest of can't read your mind when you change the context of the discussion without letting us know.
The original article was talking about standards in dating, specifically in the context of the right to reject someone you find unsuitable.
Not "standards" within a relationship you have already accepted.
Hope you have a good weekend too.
