Most men are selfish...
In most cases, they pay more attention to their feeling, their comfortness, they do not care what the women want, and their comfort feeling is superior to the responsibility to the family and what they promised at marriage...
Let's see, if this guy found a lady earning one fourth of his salary later on, he would not be able to stand that burden too, the financial burden, the unfairness of the contribution to the new family. I am 99% sure that he will ask for AA and separate account...and divorce...
For men like him, no case can make him feel comfortable.
Best wishes,
