My anger and hurt have gotten so bad that our friends called a meeting for us to talk it out

Which suggests that she's told everyone else why she's pissed, but nobody has told the stove buyer? Interesting. I suppose that a "Wow, that *is* a great stove! I'm going to get one too!" might have smoothed things over last year, but I doubt it.

In a way, I feel a little for LW -- it's no fun when a friend can afford your dream house/car/furniture/speck of dust and you can't. I think the heart of the letter is envy, not betrayal. But I doubt LW will ever acknowledge that.
