That sucks, but you know exactly what's going on here. You know her and exactly why she's upset better than anyone here. I trust my personal judgment and I'm sure she does as well, so in a situation like this I would just sit and ask myself "Will she(he from her POV) honestly learn her lesson from this?". She saw the way you acted, heard the sincerity in your voice, and saw the disappointed look on your face. Hopefully she will answer herself "yes" to that question and that's all she should need instead of keeping herself upset and picking at other stuff. Good luck
