You should care more about your man's engagement ring. It's the ultimate symbol of commitment when a male gets on his knee and offers nothing less than his undying commitment and love to you in the form of a precious stone encased on a ring molded specifically for the dimensions of your ring finger.
Here are my objections:
If/when I get married, that person will probably be making around 6figs. If they follow the 3months rule, that's a LOT of money. I'd be nervous walking around wearing that. If for some reason I end up with a multimillionaire (read: any given getbigger) then sure, get me a fat ring because it will be a drop in the ocean.
Btw my ring size is 5.5, feel free to send me precious stones, I'm a starving student, kthx
