Pardon me, but from my point of view she has the situation backwards. Not fitting the mold of these other mothers means she is actually doing everything right. In fact, not only isn't she a bad mother, but if her theory about the other women is true, I guess I have no choice but to label them not only bad mothers, but also bad wives.
Here's the problem: While their libidos may be lacking due to this newly refocused fervor, I would guess that does not hold true for the sexual urges of their husbands. And if these men aren't finding satisfaction at home, they'll eventually turn elsewhere. I'm not saying that sex is the be all and end all of marriage, but it is without question an essential element of the glue that keeps couples together ‑- and the absence of sex will seriously weaken the bond. If there really are so many women who never transfer their energy from their children to their husbands to keep their sex lives strong, then it's no wonder that the divorce rate hovers around 50 percent.
