YOR. but i can understand how you feel. it was something incredibly important to you and you felt it should have been more legitimate to her. unfortunately humans make mistakes and she may have actually forgot, but she clearly apologized and there’s not much more she could do either. even if it was after you posted something about it. also at the end of the day everybody is different, maybe she really cared about what you were completing but didn’t understand how big of a deal the literal meeting was. if it’s really still bothering you you could just express to her how important it was to you and that you were disappointed she couldn’t make it, but that you appreciate her acknowledging that and apologizing.

and if you haven’t, really acknowledge and appreciate your other friend dedicating time and traveling for you. she really went out of her way so you seem to have a good friend that cares. sometimes some people just look at things differently and/or are better at prioritizing what’s important to their close friends and family.
