Yeah - and the why is the bit I was getting at. They have a core value disagreement here, it's likely to be a common one given sexual selective incentives and behavior. I'm not making a moral judgement, but that's likely the truth.
It also sounded like she didn't want to work again - it's unclear if she wanted them both to work, or just for him to work. The podcast I linked is pretty good, men and women often cheat for different reasons, but her motivation here is a pretty textbook example.
His comments are also in the context of her cheating on him and a breakup, so unsurprisingly skew negative.
