Anyone else give each other child free, spouse free weekends? friends/co-workers said it's strange.

My wife and I have been married almost 11 years, I'm 33 and she's 38 and we have 3 kids 10, 5 and 3. We have an amazing marriage, are happy and go on several dates with each other per month.

The idea of a child free/spouse free weekend started because we got a little jealous of our divorced friends. It seemed like they'd get the best of both worlds. The happy family sometimes when they had the kids and then the freedom weekends, when they'd drop the kids off with a trust worthy biological parent and then do whatever they wanted for 48-72 hours. Impromptu trips, gardening, gaming all day whatever.

So I pitched the idea that 1-2 times per year we do a spouse free/child free weekend like divorced people. I'll take the kids to my parents Friday after work and return Sunday around dinner, and she would also do the same on a different weekend.

The rules are -

1. no long trips trips that could cause you to be stranded in an unsafe place.

2. No cheating

3. You get 200$ cash for anything you want to do like shop, order out w/e.

Well we did it. My weekend I hit the gym twice a day, ordered pizzas and played Skyrim and world of Warcraft ALL day. Her weekend she hit the gym, gardened, misc tasks, read books and watched a few movies I wouldn't have liked.

It was such a success I told a few friends at work about it and they said it is just getting us both used to the idea of not being together and to watch out. They also said they'd be worried about cheating eventually.

Does anyone else do something similar or is this really that weird?
