So in short, I seem to have been ghosted by a close friend whom I have known for over six years. We had been very close, my DP and her ex also knew each other, and the four of us hung out many times until her divorce a few years ago. We both have busy jobs so don't see each other often, and lately I have been a bit unwell so I haven't been available very much. Anyway, I have tried a few times over the past month to call/email/text and even send facebook messages, all these are read, but zero response. I have straight out asked what was going on, apologized for perceived slights, but no answer to anything. She does post on facebook and instagram quite regularly (and seems to be living her normal life, no disasters or anything) and follows me as well, and I haven;t been blocked, just completely ignored. I have been going through a spiral of weird emotions and don't know what to do. This was a friendship I cherished, and it's not like we had a fight or a fallout of any kind so I am not ready to just bin this relationship for no reason.
Anyone has had an experience like this? Why would anyone do this? I can't stop thinking and guessing. Is there any other thing I can do?
