I think it's normal for people of both sexes to go through a period of bitterness and anger after a divorce. The point is to get over it, after awhile.
That said, she's right about one thing: the pool of available potential spouses is smaller for divorced women of a certain age than it is for their male counterparts, because many divorced men either don't want to remarry (and who can blame them?) or they want a younger woman. So the rate of remarriage for women in their fifties is something like 1%. She would face a life of loneliness even if she had an angelic temperament.
Anyway, cut her some slack. She's lost her kid. If my husband had dumped me for a neighbor woman and then I lost my kids, I'd be bitter too.
My wife and I came very, very close to the brink. The end result is that we changed our lives, left our six figure jobs and focused on each other and our kids.
Now, almost three years later, we are more in love, better communicators, and we are going to make it.
After this time, I am more spiritual, committed, and I know we can handle anything as long as we work at it together.
"Anyway, cut her some slack. She's lost her kid. If my husband had dumped me for a neighbor woman and then I lost my kids, I'd be bitter too."
She isn't bitter because she lost her kid and her husband dumped her.
Her husband dumped her and she lost her kid because she's a bitter, self-obsessed person.
She created her own mess. She deserves no slack. The only thing she deserves, from the looks of it, is to be alone for the rest of her life so she doesn't inflict herself on anyone else.
