I want to spend money against my wife's wishes, after she seized my cards
Why are you retaliating against your wife and spending money after she wished for you not to spend it?
She can't tell me what to do with my money.
She is just trying to protect your family from financial hardship. Look a it from her perspective and follow her wishes.
She doesn't have a reason to do what she does.
I feel like you're gaslighting her when you say that she has no reason for her to do what she did with your cards, as she may just be very anxious and worried about how you spend your money. I suggest that you don't try and do anything to her, and just try to calmly talk about your expenses and financial boundaries with her so that she will be less inclined to do anything drastic in the future.
