Husband says war will rage in our house

My husband just told me he’s going to make life hell and wage war throughout the house because I’m involuntarily (scheduled) working 5 Saturdays in a row. I don’t get a choice in the matter. I work in healthcare. Normally I work every other weekend. The number of hours I work hasn’t changed either. His reasoning for wanting to be an asshole for the next few weeks is because I would say something when he would voluntarily pick up a weekend route last minute (Friday mornings). I would say something as it was summertime and we had plans to go do stuff with the kids. It’s winter time right now and we hardly go out when it’s cold.

To add to all of this, I was in nursing school full time and dropped out because he complained that I didn’t have enough time for the family between full time nursing school and a full time job. This is after he encouraged me to go to nursing school. We both are volunteer firefighters and I’m working on being an EMT. The new complaint is I don’t have time for the family and all I care about is work (3 -12 hour shifts) , EMT class (every Wednesday 6p-10p and second Sunday of the month 9a-5p), and the fire department. I work on homework on my days off during the week while the kids are in school and I only go on 1 or 2 calls a week. I’m the primary parent. Before I started working 12 hour shifts, I was the one picking the kids up from school, running the house, cooking meals, and all that jazz. Now that I work 12’s he has to do my housewife tasks 3 days a week.

This all really started happening spring 2022 when I decided to leave my insurance claims job to pursue a career in the healthcare industry. He never had a problem prior to this. Divorce isn’t really an option. I only make $20 as a CNA/Med Aide working 36 hours a week. I can’t afford to live on my own supporting 3 kids. He’s also threatened before if we ever got divorced, he would make sure I wouldn’t get custody of the kids.
