There is a huge difference between what women in their twenties want from men compared to the ones hitting 30. I can't even count the number of females I know who ditched the guy they were hot for at 25 the minute they turned 30. By 31, they are up to their elbows in a relationship with a guy holding a steady job, Some women figure it out a bit earlier, like by 25, but they are few.
At 23, I got ditched by one of the girls mentioned in my post above when she turned 26. Her exact words to me were that she didn't have time for my games anymore. Good call on her part; she hooked up with a dude who was 36 and then, "formed an advertising agency in Chicago with the guy she married and now lives on the Gulf Shore in a $5M home somewhere south of Tampa."
Guys kind of do that in reverse. At 20-30, depending on their own maturity level, they want the more established female, a professional who has her shit together and maybe even owns a house already. But, at age-40, they suddenly want some ditz that stands out in a crowd. By 50, they realize that hooking up with the eye-candy was a mistake but learn to live with the consequences, since divorce now is too expensive. So, even if she's boinking the tennis coach, the guy looks the other way.
