So by this theory women (single, childless) should be easier to date in their 30's, but in practice they are harder. They don't need to rely on a man because they have their own money, and have 12-15 years of independent decision making and are not going to let "some guy" tell them what to do.
Up until now there is always a few guys willing to treat them like a princess, if she keeps her mouth shut and looks good on his boat or in his pickup.. That doesn't cut it for her anymore. And they have met and dated (once) all these Basement dwellers who moved back in with Mom and are looking for someone to cook them breakfast and do their laundry. All their friends are married and too busy to go out to the places they used to go. Her social circle shrinks...The only growth comes from work and newly divorced people her age.
She can't date a single dad long term, because she has no parenting experience, or qualification or desire to mom a kid or tween. She's never bonded to a child. She hates competing for single dad's time with his child, and career, and his buddies. She gets P'n'D'ed a lot. This is why I DQ'ed the single/divorced childless women as LTR's .
I think single childless guys in their 40's can have success with 30 year old childless professional women if they date them on weekends and live separately. He is gonna have to earn more than her for her to respect him. They are each others dates for events for years but never move in together because they are both too independent...
The women who seemed to me to chase harder were mothers in their 40's trying to relive their younger carefree days. Often their 30's were hell as a single mother to little kids. Especially if they didn't have a support system of family to help with them. Once those kids are in High school, they can meet the divorced dads who appreciate their struggle, (and have a little more time since kids are kinda independant) .
Just my observations within my social circles....
