Love and emotional vulnerability are one topic. Specific divorce laws are another topic.

As a thought experiment, imagine pushing the divorce laws even further in the existing direction. Imagine a law saying: "if a wife kills her husband, this is not considered a crime, and she automatically gets all his property". Wouldn't this make men even more emotionally vulnerable? Wouldn't this make marriage a more exciting adventure? How much more attention would we pay to choosing the right partner! Definitely seems like a move in the right direction. (just kidding)
