Actually, they don't just leave disrespectful and neglectful husbands. They leave the ones that love them too.
Now they may not know the right things to do. But that doesn't mean their husbands don't love them, don't respect them or neglect them.
I don't think anyone, man or woman marries with the idea they are just going to ignore their spouse.
They may get discouraged because they are doing the wrong things. But then there are only so many times a husband can ask his wife what do you want me to do, only to hear, "If you loved me, you would know what to do."
Ask most guys and they'll tell you they are showing love by being there with her, by having a good career, or taking care of things around the home.
Now if those are not her top emotional needs, he won't rack up many deposits.
But it's not because he's not working at it, or that he doesn't love or respect her.
Have any of these women asked their husbands what they are doing to show their love?
They are probably so close to the solution, but instead of actually respectfully communicating, they make the ultimate DJ and assume his motives, assume they know better than he does about how he loves her, and she ends the marriage. She ends the marriage to a husband who loves her, and she didn't even recognize the love he showed her.
It's not just the make yourself happy thing, thougth I think that's a big contributor. I a woman IRL who would leave her disrepsectful and neglectful husband asap if she could afford to do so. But she can't. She fears they have no marketable skills to make a decent life for her and her kids, and her solution is to just put up with poor treatment.
I think the realization that, nowadays, women don't have to put up with poor treatment just to be provided for anymore. And you'd be surprised how many times I've heard older women say in passing that the only reason they stayed with their husband is because of money and the social stigma of divorce. Both of those barriers are now removed.
