Finally done it. My parents have split up which means my contact with mum can stop without affecting my relationship with my dad. My mum emailed last night saying she wants to come and see me. I replied saying I didn't think it was a good idea as neither of us had a thing to say that the other wanted to hear, then I blocked her email address. I guess she could text or come round but she hasn't done that for years.
Should I have specifically said that I want to cut contact? Presumably she will reply to the email and wonder why she gets no response. I don't want to be cruel, just want to keep her away.
