Everyone gets divorced anyway. Let's stop playing fantasy make believe like things last forever and enter into reasonable, sustainable contracts with set terms about duration, assets, and expectations. The idea being to redirect the societal expectation of making such an agreement to two people making a conscious, reasoned choice to raise a family together rather than two people caught up in emotions making clearly unsustainable promises to each other.

For the record, I've never been married. Just done an awful lot of observing of older, clearly unhappy couples, who clearly feel stuck. I don't get the impression our already very high divorce rate is even as high as it would be if everyone who wanted to get divorced felt like it was an option.
