I see a lot of posts on here about making sure to get married before having kids etc. to avoid being left in a bad financial situation in the event of a breakup. But if I, as the woman in the relationship, was earning an order of magnitude more than the man, and had enough saved up to be able to live comfortably for a very long time, would you still advise marriage? Given how much people can change over time, I don't think I'd ever want to take it for granted that a partner would never leave me. Are there any legal protections that would still make it advisable from my point of view?
