When I Have to Choose Between Work or Family

I work as a nanny, and twice a week I have to work late because my boss goes out. Nobody wants to come home at 2 or 3 AM in the morning, but what can I do? I need the money to help support my family. My husband on the other hand always complains that I don’t spend enough time with him, etc. “Well, if you were Bill Gates, then I wouldn’t be doing this dead end job, would I?” I don’t have the heart to tell him that, though.
