I was a SAHM for 13 years. When I went back to work, it caused a lot of resentment in our household for the first 2 years. I left for a week on a trip and left hub in charge. He was working plus taking care of the kids and the house (honestly 1 week alone isn't remotely close to knowing the workload won't stop for years), but he had such a hard time that he did start to help more.
It's pretty disgusting. I've raised my boys way better than that.
