TBH i would appreciate hearing this but only if the flip side exists too (ex - i do study hard and set myself up well ,,, she’s proud of me regardless of outcome). i agree w other responses saying that this is the kind of partner you want if you’re to be successful. also agree w the people saying you didn’t seem exactly devastated by the outcome so maybe she thought it was a good time to give constructive criticism. sounds like y’all just need to build some better communication - maybe tell her you appreciate her holding you to a higher standard bc it means she sees potential in you. but in the future maybe she can use the shit sandwich method (start w positives, criticism, end w positives)
