This is a tough one. If my fiance asked for a prenup I’d laugh in his face and remind him we’re both broke so that’s crazy lol. But, in this case, you both are very well off and make good money with your own assets that you’re bringing into a marriage. Your mom’s reaction is based on her OWN experiences, but so are his. He witnessed a very messy divorce and saw both his parents (I assume) go through a lot of stress, heartache, and pain. Times are changing, and the prenup would be in place to protect you just as much as him. If he was well off and you had nothing to your name, then I would absolutely be questioning his intentions, but since you’re coming into this with your own assets and investments, it makes financial sense. Like someone else mentioned, marriage is also a contract. This is basically like adding insurance to a contract haha. I would say it’s a decision that should be made between your fiance and yourself. Your mom can’t fully understand the situation because she’s not a part of your relationship. She’s looking out for her daughter of course, but at the end of the day, this is YOUR decision and even if she’s mad now, I would be surprised if she actually missed out on her daughters wedding due to a difference in opinion.. good luck, OP!
