My husband and I are not married. What should I do? Shouldn't couples work together?

Of course, husband and wife should work together, but the premise needs to be based on a good relationship between husband and wife. How can two people work together if they don't get along well or even have contradictions? The power to make two people work together is not the form of marriage, but the actual feelings. So when they are not United, it shows that there is still a problem with the relationship.
