How Does a Man Cope With the Humiliation of Living on His Wife after Losing His Job?

First of all, you need to let go of the idea that there’s anything humiliating about losing a job. There’s not. Life a vast, and its vastness will help you have another one. Don't loose confidence within yourself. That is the first thing to do after losing a job. Just don't question yourself.

It’s only “humiliating” if you’ve internalized gendered toxic, sexist bullshit about how men and women are “supposed” to perform their roles—that men are “supposed” to be the breadwinners and take care of “their” women during each and every condition.

In reality, men are just human being, and women are the same, and when you are a person who doesn’t have a job, it’s nice to have other people in your life who can help you to find another way in this vast universe, and help you till the time you can get a job. There’s nothing humiliating about that at all.
