I think the "death do you part" should be removed from marriage vows - as this is something which is routinely broken by most marriages. If it were some tiny number like 5%, then it would be reasonable. People should vow something they can actually stick to, like "I would like to be with you for the rest of my life" at the time of the marriage which is an expression of intent and not legal obligation. Relationships should be an "at-will" arrangement at the convenince and benefit of the participants. I also think that people who move in with each other should automatically be granted the title of "Married", becuase what else would change if they actually got married besides the big expensive party? Living together is the ultimate commitment - it is not a "step" along the way, you have arrived. Yes, you could break up at anytime, but society has proven that even if you go through with the big party that you can still break up at any time which is initiated by the women nearly 90% of the time. That marriage provides any security is entirely an illusion and a big fat terrible lie that we tell ourselves. And the worst lies are the ones we tell oursevles. If we were just being "realistic" about what marriage means (just living together), then that would make it a whole lot less scary and men would be a lot more open to labeling their relationship a "marriage".
