The men who want women their own age pair up in their 20s. Either stay together or get divorced mid 30s to mid 40s. When they get divorced many have kids and dont want to take on more children so the age of women they look for is pushed down unintentionally by rulling out single mothers.
Men who are single in their 30s onwards that had no luck with women their own age so aim for younger women with their higher economic value providing benifits that they didnt have then and dont appeal that much to women their own age or aim for younger women because they still lack the social skills and younger women with less experience are easier to seduce.
So a women in her early 30s looking for a good guy needs to look at men in late 30s who is divorced or a man in his early 20s looking for their first serious relationship (bit of a gamble). Men in their late 20s plus looking for their first relationship are going to lack social skills to provide what you need.
