There are plenty of women out there who would be happy to date you. You are the one filtering them out. Consider women over 40 and women with children. Those groups have huge problems finding men. Works both ways.
I hate to sound like a terrible hypocrite, but I do have to apply filter enough that I'd be able to honestly say I found them attractive. My standards are actually not all that vastly high to sound like a terribly shallow person.
As for women w/children, I wouldn't on the basis of having had a step parent during my upbringing and the various weirdnesses that involves so I'd rather be single than be in that position.
