I think this is TOTALLY normal. Whatever we do for a living feels like "work". We don't want to work when we get "off" of work and go home. Remember the saying "The cobblers children had no shoes"? This is exactly what it meant. The shoemaker never got around to making shoes for his own family.
My ex-husband, back when we were married, completely tore out a bathtub and sink, as well as flooring in our master bath. He was a contractor, doing this for people everyday. I could NEVER get him to finish OUR bathroom. It stayed torn up for a year until we decided to move! I guess it no longer felt like an imposition to him since it was now for someone else. Go figure.
I found that coming home and taking just 30 minutes for myself to rest, change clothes, and skim over the mail gave me a chance to wind down from work and wind back up to take care of my kids, when they lived at home. I would catch my second wind and get dinner going. I made sure all were in bed by 9pm if they were in elementary school, 930p for Jr. high, and 10pm for high school. It was a strict rule, so I could have some ME time. I was a single mom at that time and needed a breather, like most. Good luck! B. P.
