Dear Prudence,
A few weeks ago, I had a falling out with my best friend from uni, “Mary,” over what basically amounted to poor planning. I’d canceled plans with her twice: once when I realized her early birthday lunch (with us and her other old school friends) fell on the same weekend as the event I’d bought tickets for at the start of the year. I felt awful, apologized, and offered multiple alternatives, but she turned them all down. The second was a dinner with Mary and her niece. They’d rescheduled a few times, and now it fell on the same night as another friend’s going-away party. I chose to go to my friend’s going-away party, since it would be the last time I’d see her for three months. Mary made a big deal out of it and said she would have skipped it for me. I think I could just as easily have seen Mary and her niece another time. I said I’d arrange something after I got back from my upcoming work trip. I’ve been back two weeks now, we haven’t spoken, and I miss her. How do I fix this?
