In a way. Both of my husband's parents are disabled (both legally blind, and his father also has Alzheimer's and dementia, among other things), so we live with them to keep them out of a nursing home.
The problem is, his parents hate each other, but won't get a divorce, so they just stay miserable and fight with each other all the time. We both grew up in homes with constant (and hateful) screaming and yelling, and there is no way we want our kids to have to grow up with that.
We keep "threatening" that we're looking to move out and keep their grandkids from them, not to be mean, but for the sake of the kids. Unfortunately, they always try to talk us into staying, and because my husband doesn't really want to see them end up in a home, we do.
It's really a bigger situation than that, though. There is a lot of stress brought on by his sister and the rest of his (local) extended family. I just hope that one day it doesn't become too much for us to take.
