I think I had a burnout at home. It was just too much: 90% to 100% job, 3 kids, house, and the constant feel of (self?) pressure to make it all better, always be prepared and such at home.
My wife and me separated almost a year ago, and since then share the care of our kids by 50/50. She works a lot (80%), I work a lot (90%). It only works because the kids go to school, I can work from home 2 days and we have grand parents that help when in need.
I just feel so free and unleashed. She too. And the kids are fine as well.
Finally no one is putting any pressure on me at home except for myself. I have such a great time with the kids and I really enjoy it. And I still love my job, as I always did, working more or less 8.5h a day.
Anyway what I wanted to say is, that you can also have a burnout at home. I was such an emotionless dead guy.
I'm not sure there is no cure, and I agree that whenever I feel this "pressure" again in a new relationship (not that I had many), I feel like I'd like to run away and stay single. Which makes me sad. But on the other hand I rarely was as happy and free as I am now.
