I think whisker pretty much summed it up. I don't think even women know what they want. Personally, I think most of them just don't want to be tied down in a relationship until they're older. The "nice guys" tend to remind them of commitment or marriage. The a--holes are just someone they can use until they're ready to settle down. Then again, some women can't function unless they're in crisis mode 24/7. And some are just absolute attention wh*res.
