Guys your age who are desirable are settling down with early 20 somethings (the minority that have their shit together) rather than wasting their time courting someone who is both infertile and has a high opinion of themselves.
I would never date a woman in her thirties unless I didn't want to settle down and have kids. And I say this as a guy who did a long term relationship with a woman in her thirties before eventually realizing the error of my ways.
Women date and marry up (in terms of status). Guys marry youth and childbearing potential. An attractive woman with lot of money who's leaving childbearing age is going to have a really hard time matching with most guys-either they are too low status or they can do better, with a huge gap in the middle for the guys that are both too low status and can do better.
