After 2 years of this (while we were still dating) I asked him how we are ever meant to go on a vacation together, if his PTO is spent at home with his visiting mother? We agreed to save PTO for a trip to Europe we took in 2023 and he agreed to tell his mother he couldn't take off from work every time she visited. In my last job, I was able to work from home 4 days a week and every time she visited, she sulked all day like a puppy who's had her toys taken away.
