I need help right now lads from all of you, this is serious!

So, I'm in a big problem right now. My wife came two days ago to me crying and saying shit like we need to rethink our marriage and I should stop spending money on warhammer 40k. What the fuck should I do? I kept telling her everything is fine, we have enough money for bills and she kept yelling and crying. Any advice? I don't want to sell my warhammer collection and she started threatening me with divorce ffs.

All info:
>wife and I work as accountants
>2 days ago she comes to me crying, threatens me with divorce, tells me to sell all warhammer collection and grow up
>her mother, which she didn't talk to for 2 fucking years started calling her again and they discussed on phone hours for 3 weeks
>we got some bills, I told her we have enough money for them, she started screaming
I don't get WHAT THE FUCK IS GOING ON WITH HER
>her mother hates me
Oh yeah

My collection is worth 60k alone

Need help now!
