What Do They Have against Type Three?

I found the following at baristanet:

In the world of dating, women of a “certain age” are faced with less than stellar prospects. Every available female over the age of 40 knows the three types of men:

• The newly divorced male, who will only date 25-year-olds.
• The still married male who is looking for a little fun, and will only date 25-year-olds.
• And the male who has never had a meaningful relationship of any kind, who would date anyone.
