Oh, ok. I get where you are coming from.
I don’t know if there is one way to view it, but here is how it is for me.
Predatory - in my eyes - only applies if there is some sort of mismatched power levels, income, or levels of maturity.
So - a 60yo hitting on 45yo - isn’t predatory. Both are well into a grown up phase of their lives. And - of course - a younger person looks more attractive to the older person, especially in that age bracket.
PC or not - but an average 45yo (man or woman) is more attractive physically than an average 60yo.
So - why wouldn’t he try to approach a younger woman 🤷🏻♀️....
However - a line manager of 35 dating a subordinate of 21 is verging on a bit of predatory.... And most very young women in these arrangements say - not in my case, I was mature, etc. And yet, still, wherever there is a power imbalance - there is always a bit of question there...
As to dating as a mid 40s woman...
It all depends on what you are looking for in dating.
There is no reason why a fun and physical sort of encounters with 30yos can’t happen between a younger man and an older woman. So - 30M, 45F - why not.
It won’t last as a relationship, for many obvious reasons, but as a short term thing it can work.
I’d not worry as much about the ‘rule’ or what who thinks. I find that dating after 40 can be fun again. There isn’t a pressure and time scale to find a baby-daddy that spoils dating in the 30s.
So - past 40, you can date like a 20yo again - just for you. To have fun. To meet people.
