It seems as if some feminist women raise their "standards" for a partner as they age. As we age we don't have as much to offer a mate in the appearance department. Yet these women act they are still 25 and still vibrant. Men in their 40's and up are tired of trying to live up to these "standards".
If women in their 40's and up , want men to meet their "standards" expect men to be alone rather than putting up with this sense of entitlement these 40+ women expect. Women outlive men by 5 years anyway, don't make it worse by expecting men to cater to all your "standards" . It's only a recipe for you to be alone. You may be one of those women who complain to your female friends about how there are no good men around.
