Such a small thing?? That her husband won’t make himself his own food and depends on his wife like a child? Yikes!
Yes, there might be another problem and this might be the last straw for her.
If you are in a relationship right now or even if you aren’t I would do some research on mental load and the effects that has on a person.
If you looked on my account, you'd know that I'm married. My wife and I are aware of mental load. It's bullshit, if you suck it up for work, to go to work for 40+ hours a week, then suck it up at home. If you don't want to deal with any problems, then be single. Relationships are easy and you all think it's supposed to be easy.
