I wish I could get them to understand that they don't need to figure women out! They just need to learn about and accept the woman they want to be with. We absolutely cannot seem to make these guys understand that women are not a separate species of humanity or a monolith, who are all the same. We share a lot in common but are as individual as snowflakes, and thats how women need to be approached.
The men who have women in. Their lives treat them like people. Not puzzles to be solved, or vending machines to slot coins into to get sex out of them, or like some new extraterrestrial species. And ascribing to ALL women the bad behavior of the 3 or 4 women who might have hurt them in the past is never a good look.
