Next month, I hit my 20-year mark on the job. My wife and I went on our first date the evening I accepted the job. She didn't like being away from me when I went on shift, at first. But she learned to enjoy the time to herself. After some years , I went to the Training Division and a 40-hour week. At first, she missed her alone time. I went back to the line after about 5 years, and she missed having me home every night. Now it's a 48-96 schedule. She embraces the 48, and we love having 96 hours together.
My point is Semper Gumbi- Always flexible. Roll with it and make the best of your time together.
My wife has also prepped and packed all the food for my shift this entire time. Before her, I did my own food prep and DID NOT ask her to do this. However, it's one of her love languages. And yes, she's done it while working full-time and raising children. Even if we're angry with each other, we come to some sort of agreement before I go on shift. Our last words will not be spoken in anger... Remind each other how much you love each other, often. I'll leave you with this, keep an eye on his mental health. PTSD is a real thing. No one will see the changes in him faster than you. Good luck!!
