DP had her teeth done a couple of years ago. She's always hated them, they're a bit skewiff and discoloured, so she had veneers done on the top row last year, because we could afford them
Objectively, she looks better. And she's more confident, and smiles more freely.
But. I don't like them. I'll never say anything, but I miss her smile. She has a nice smile now, but it's not the smile I've spent 20 years with, not the smile I fell in love with. I'm happy she's happy, and at the end of the day it's a tiny part of her, so I'll live with it.
But if that was just the first step, and suddenly there was something else she wanted done, then I can see myself panicking and saying something. If she had a boob job like you're planning OP, then maybe it might be important enough to say something, and maybe I'd panic and not say it well. I love her boobs, and if they changed, then they wouldn't be hers any more, and yes, that would bother me, in the same way her teeth do.
Your husband has been clumsy as fuck @lulubellaa , but he's trying to tell you he loves you, and that these cosmetic procedures make you a little less "you"
