Hi Chihuahua,
Sometimes it is so tough! I have put up with my husband and he with me for 23 years now and it is a constant job.
Why not go on strike for an hour or two? Hand over the kids and either leave and go shopping or take a long bath with a do not disturb sign. You need to allow yourself some "me" time. When my kids were young we used to joke that I had something going with the Walmart greeter because whenever I needed a break I figured out something I needed at Walmart.
Good luck!
