I'm not sure why you think this is some rare happening, because it's not. A lot of women have and can accomplish this. Everyone's situation is different, and you can't place every woman in the same category because you don't know everyone's story. To be forever alone just because you now have a child or have to wait forever until that child grows until you can find a partner, that's just ridiculous. Give a woman credit, a lot of women are responsible when dating and won't even bring that person around their child until they know that they have something serious.If we looked at statistics I bet you are the exception tof he rules. Yes, we all have different opinions but can be civil enough to rise above.
It's sad you're putting so much blame on women while you're excusing any blame or responsibility on the man.
