Don't take this the wrong way, but this situation actually happened to a distant family member of mine this month.
She is married to a wealthy doctor. They went on vacation, and he put the smack down on her. They will undoubtedly get divorced, but she hasn't filed any charges.
If she does, he goes to jail, likely loses his license, loses future income, and she is raising kids as a single mother.
If she doesn't, all that future incoming money will be distributed to her and the kids. And by all accounts he is a good father, so she won't be a single mom.
Now, are you saying that it is disgraceful and atrocious that she chose the path that benefits her the most? I'm not sure I would label her decision that aggressively. In fact, if I was in her shoes, I would probably also choose the path that benefits me more as opposed to the seeking justice path.
I'm not even saying there's a right or wrong in the women's decision, but to call one decision disgraceful (which i note you didn't call the decision disgraceful, but instead the suggestion of that path disgraceful) is a bit aggressive.
Many women do make that decision.
