My boyfriend keeps telling me not to have surgery ㅡㅡ; What should I do?

There's less than a week left since I made an appointment for nose surgery.... I told him to get it slightly because my nose is low and a bit boxy, but my boyfriend says he'll regret it, that it'll look weird, and makes all kinds of bad comments. ㅡㅡ; He's such a bad guy, he always makes fun of me for having a low nose. I'm doing it because of stress... My nose is cute right now... They're giving me a bottle and giving me medicine... I'm insomnia from stress because I keep doing that haha ​​They keep telling me that I'm going to regret it , so I'm shaking again because I have thin ears ㅡ,.ㅡ The date is getting closer ㅠ ㅡ
