Is she jelous, truly? Or is she warning the younger woman avout her future because she WAS the young and beautiful woman last decade.
If the "high value" man cast her aside for fresher fruit, why should the current young woman expect any sort of loyalty?
The authoe of this tripe will not be young forever either. Time marches on for all of us. This hypergamy in men is not going to work in her favor long term. Then, like all the other older women speaking to this dynamic, she'll be singing a different tune.
And some other bozo will roll up and say she's just jealous.
