From what you are describing of your husband, his marriage is to his job.

You don't have a "marriage", that doesn't happen when only one person is "there" and the other person isn't.

What about you? What do you have in your life that is "your" passion?

It is not unusual for a person to get married with an idea in mind of what they want of the other person and then learn that their idea is not what that partner is going to actually be.
