I sympathize with your views of the dating world and the differences between those with kids and those without. I don't belive you're off base at all.
At the same time, going the "with kids" route also is a complex game. While this BB may prove that there are thousands of potential partners with R skills sufficient to be the next H or W--blending our needs with those of the kids remains very very tough. I often wonder if I should just limit myself to widows or simply just wait until my kids are gone. It's one thing to date for the sheer sake of dating, but it seems most of those out there are looking for --or will eventually want-- something more. That's hard enough before kids, but a real complex one now. I'm not offering advice one way or the other, but in my world, the only constant is my kids. I helped bring them into the world and their needs must be paramount in all my acitons. At what point my needs start to balance out more against theirs I do now know; but right now I'm not even close to that point.
