AIO She spent our vacation money on Bad Bunny in Mexico

For 5 years I've told my gf to save money so we go 50/50 on ONE trip per year somewhere, anywhere and guess what she did? On her own she spent it on a bad bunny concert ticket in mexico city. She bought it without having the money for the airline ticket or bus ticket or I don't even know how she's going to get there but she decided this all on her own without talking to me. AIO?!! She wanted me to be happy for her that she did this. She did not reassure me at all that she'll have funds for us for our trip of the year. She wouldn't even suggest a damn place to go. We've gone on vacation 3 times in the past 5 years mind you and it has been amazing each time so I have no idea why she did this and so recklessly at the time.

(She isn't my gf no mo'. It's because of this and so much more.)
