Working to provide for your family is one of your primary duties. The other is being there to give your family the love and support they need from you. It's a delicate balance between the two, and one that is hard to achieve. Reassure your wife you want to be there and ask her to think of creative ways of cutting back on your spending to free up more time for you to spend with your family.
If work at a job like that for 25 years. My first wife encouraged me to take the job because of the money. Divorced me a few years later because I was never home. Met my second wife while doing this job said she could handle it before we got married. Couldn't handle it after awhile. The main regret I have is the time I lost with my kids as they grew up. If you have kids. Get work where you'll be home more. They are the most important thing in your life.
We all have experienced the added stress of work related issues and how it sometimes conflicts with family time. Problem is, some of us have jobs that demands an extra ordinary amount of time, more than an 8 hr day, 5 days a week. ..which limits time and quality of time spent with family. I understand your wife's dilema. I've been there, myself.
Husband worked two jobs, I worked .. kids were in school and in bed by 7 .. he often came home after they were in bed...dog tired. And this was a man who absolutely adored his children. It ate him up that he couldn't spend time with them in the evenings. I mean .. although he was a younger man then, he was over extending himself to make a better life for us as a family... BUT .. I was always waiting for him and the door to greet him .. and he was always happy to see me. He always walked in the door of our home with a smile on his face.
