seems like shes violated one major rule in relationships - TRUST. she didn't trust your opinion and what you said about her assets hence why she still felt insecure, on top of that she took your savings and got a boob job all behind your back. you should still talk to her to definitely put it out there and make it clear that what she did was not okay at all. you could ask her to pay you back and then leave her/ stay in the relationship but considering you have now lost trust in her and find her unattractive i think its best to leave the relationship whether you ask for your savings back or not. (just my opinion).
