I was divorced twice before I ever started at UPS. And now I have been with one who keeps me around for 6 yrs, and we lived together (yes in sin, and it was luscious) for 6 yrs. So while the hours can suck, its the person you are with, for better or worse, that makes the marriage.
We look forward to my time off, and we make the best of it. Divorce is not even in my vocabulary, Im not starting over again. Some of the guys I work with totally spoiled thier wives only to get the big bone. I say date, and see how the other handles it, if they are sniveling how they need more time together, then they are too needy to be married to anyone, and definetely not you. Move on friend. If they handle it well and enjoy you, then it can be great, the last thing anyone needs with a demanding job, is a needy spouse. As for the kids, well, you knew what the hours were when you got into it. Some families can adjust others cant. I dont see a way to fix it in this job. The hours unfortunately are for most positions from 8 or 9 to 7 or whatever, and that is the day.
