>>10243546This right here is why you always sign a prenup if you are getting married, anons.
It's your stuff, you should be able to put your foot down and go "If this is suuuuuch a big deal for you, the door is right there. Sad you are behaving like a kid over some toys, my toys"
I'm assuming you have no such thing so I would suggest renting a storage unit and keeping your lego there, and subtract whatever they charge you from the money you give your wife.
Let her feel like she won so you don't get more problems, but in reality the only one losing anything is her. Good luck, anon
