AIO 11 year friendship ended?

first photo: she unsent all her messages and left just mine. She has deleted her instagram, blocked me everywhere and said we can’t be friends because I don’t support her staying with her abusive fiance. She has been with her fiance for 5 years and they recently got engaged right after she tried to end the relationship. She invited me to their house while he was visiting family out of the city, and she was beside herself with grief. As soon as I went home, they talked and she decided to stay with him. I think she was manipulated. She is very angry with me for sticking to my original feelings about the situation, and I don’t want to budge. Someone doesn’t change in the matter of 11 days when they’ve been displaying this behaviour for years. She got engaged and posted the ring on her story while we werent talking. We’ve been best friends for 11 years. This is the only person she’s ever dated. She has no other friends except for me. I’m dating someone long distance and visited them for the first time. We live in western Canada, and my partner lives in the eastern USA so it’s a big trip. It was also my first time flying alone and my first time flying to another country. Also my first time flying in 14 years. She didn’t ask how it went, didn’t check in with me, and barely replied. Then, she blocked me last week and messaged me saying she can’t have me in her circle and unsent a whole bunch of messages before deactivating her instagram and blocking me. I said nothing about her partner since our original conversation 2 months ago. I didn’t bring it up again. AIO?
