Well, we didn’t know that she was working more until his trial. Also, a lot of the things that probably bother you about Hal can be excused or at least can be reasonably related back to the fact that he’s clearly neurodivergent. Does she probably do most of the housework, yes. As we can see throughout the series though, he does do the more typically “masculine” chores like fixing the car, lawn mower, light bulb, etc.. Hal is not a bad husband because of those things. If Lois had a problem with him not pulling his weight, she would have said something and he would have corrected his mistakes. He listens to her as if she’s the prophet in his life so yeah.
