Friendship advice

My friend has her wedding set for June 2026. I am a bridesmaid in her wedding. I got engaged September of 2025 and set my wedding date for September of 2026. I asked her to be a bridesmaid in my wedding as well. My fiancé and I are on a tight budget for our wedding, and are covering the cost of everything ourselves. My friend told us in the beginning of January 2025 that she was thinking of doing a weekend long destination bachelorette. At that time I started saving money for it, but was surprised with my own engagement in September 2025. Since then I have had to use all of my savings to cover the costs of vendor deposits. She let me know just a few weeks ago that the cost for me to attend her bachelorette would be $900+ for flight, Airbnb, boat rental, food, drinks, etc. I told her that I was unfortunately unable to attend as the cost is something I simply cannot afford. Her Bachelorette is in March. After telling her I can’t afford it, she got mad and told me she is no longer going to attend my bachelorette in August because she no longer feels obligated (after she already rsvp’d). My friend and I live in different states, so we both have to fly out for each other's weddings as well. Am I in the wrong for not having the money to attend? I don’t want this to ruin my friendship, but if I spend $900+ on her bachelorette I won’t be able to afford my wedding payments or potentially the cost to fly out to her wedding and the costs associated with that.
