AITA for not letting my wife use my money for a boob job

I am in my mid 30s M, my wife is in her mid 30s F. We are having a bit of a fight right now. We both make a very good income, mine is higher than hers. I make around 600k and she makes around 400k. We both save a lot, sometimes saving over 70&#37; of our income. We own 12 properties together now. We both invest heavily into the stock market. We have 4 kids together, we both have agreement that we are done with kids. Our combined savings is around 6 million dollars.<br><br>Last couple of weeks, she brought up getting a boob job. She wants to get a more noticeable size, she says she wants to look better for me. I told her to cancel, I don’t want her risking anything to get a boob job. She said it’s safe and she wants to do it. I said okay but only if you pay for it yourself, don’t touch my savings. She was mad that I said that and said she will if she wants to, she doesn’t care about the money. But I’m not allowing her to. I’m only allowing her to use her own money. <br><br>She said why would you care if I use your money, it’s ours. I said no, my paycheck is mine, yours is yours. And she got mad. She said that’s not how marriage works, you have to sometimes make sacrifices and that’s one of them. I said I’m not making any sacrifices, I pay for everything in the house, I’m not allowing her to use my money.<br><br>Then she said I’m being selfish, I want her to look good for me but I won’t allow her to do that. I was mad and said no, I don’t want her to risk her health just to look good. I want her to stay the way she is. And she got mad. She said that she wants to look good for herself, not just me. I said okay but I’m not letting you risk your health just to look good. <br><br>She said I’m being controlling and possessive. I said no, I’m just protecting her. She said I’m not protecting her, I’m just being selfish. I said fine, if you want to get a boob job, don’t come crying to me when something goes wrong. <br><br>I said I don’t care if you get a boob job or not, just don’t come to me when you need help fixing it if something goes wrong. I said I’m not going to let you use my money to fix it. She said you’re such an asshole, I don’t even want to get a boob job anymore. I said good, you shouldn’t have in the first place. <br><br>She’s been angry ever since and called me an asshole multiple times. I said fine, I don’t care. I’m not letting her use my money to fix a problem she’s going to cause to herself. AITA?
