Input: Long story short, I had a good friendship that took a nosedive after high school. About two years ago my parents sat me down to tell me they don't think she's really my friend and not to trust her around my bf. They pointed out a bunch of situations that occurred over the years where she treated me poorly but I made excuses for her because she was my best friend. Right before Christmas, I noticed that she was making a whole bunch of subliminal posts about me. I knew they were about me because they would always correlate to whatever it was that I have posted.she never came to me to tell me why she was upset but her and the other people she recruited to help her in these posts I said some really hurtful things so I ended up blocking her on all social media and on the phone. Sometimes I feel bad throwing away over a decade of friendship without a conversation first but after the conversation I had with my family and the posts I think I did the right thing. So, AITA here? Did I owe her a break up talk?
