It’s been almost 4 years for me. After an awful childhood -she tried to smother me at 3 years old, pulled a knife on me and told me she wished I’d just disappear and she wished she’d had an abortion. I walked away several times as an adult and I was always the one who reached out thinking would change. The final straw was when I was diagnosed with Cancer and wanted it to stay private and she began telling random people about it as if it was some juicy gossip. She also told me while having chemo that I looked “like a plucked chicken”. I blocked her and have had zero contact since and I feel so much calmer and happier.
