> Promising to be with someone forever It was historically more of a family obligation than a promise. We have made it more about individual choice in the intervening years, so you might see that as a promise, but these days it still isn't so much a promise to stay together, rather a promise with regards to how to deal with division down the road (e.g. promising to split the assets 50/50). Not staying together is the assumption.
