I dislike the notion of "dump him culture".
Bad wording here. Super bad.
This isn't a cultural trend. It's not cult behavior. It's not group speak. It's not any of that.
It's women stepping up to being captains of your own lives and destiny rather than chasing helplessly after the approval men and society.
It's ditching that fool's errand. The goal posts will always shift and you will never be enough. Unless you're too much.
Get right with yourself first and foremost. Your approval of yourself is the only approval that should matter first and foremost.
