Sometimes he pays attention to tradition, and sometimes he doesn't. Anyway, it depends on whether it is good for him or not. I feel that he is quite selfish.

First of all, no one has the right to ask you to do anything unless you are willing to change it for him, and this kind of thing (making you earn less than him) is actually unreasonable.

Secondly, I want to say that the man is not mature enough, or he may never be mature. He may be influenced by male chauvinism. If you want him to seek change, communication is the best way, and it will be gratifying if he succeeds. Otherwise, getting married without communication may be even more disharmonious

In fact, he just thinks that he may not be able to control you, and he can't accept that your economic income is higher than his, so you can consider finding someone who will appreciate you. Now the times have improved a lot, and there are many new and new young men like this.
