It does seem made up. I think it should be backed up with references. Also, it's really unhelpful for OP's question. It's perfectly normal for men to earn less than their SO. Statistically it would be the case in 50% of couples, in an ideal world with gender equality. Also, in any relationship, there will be moments where one person is out of work and dependent on the other (laid off, take care of kids, take care of parents, burnout, etc).
