Sorry but you sound like my mum.
We don't talk anymore because she did something very upsetting on top of her and my dad's iffy to abusive parenting technique.
I have tried to talk to her about it but she refuses to acknowledge her part or apologise and instead keeps saying things like "what do you want me to do? I've apologised already!" and turning it back onto herself in an attempt to guilt trip me. She most recently pretended to have forgotten what happened, so in her mind it's like if she says she can't remember it, it didn't happen and I should just let it go and move on. It did happen, she does remember it.
I also have had to put up with a few flying monkeys who've been given her story, stripped of facts and showing her in the best light, come to give me the second hand guilt trip.
I now have completely cut off contact and have blocked her. I don't want to know and have made that clear, yet she still sticks herself into my life about once a year. It just gives me that awful stomach through the floor feeling every time she does it and makes me sad all over again about everything.
Why won't you answer the questions asked by the PPs? If you can't give further detail no one can help you.
Like someone above said, if you have done something wrong and especially if she has communicated that to you, you need to do something about it.
Face it head on instead of wrapping yourself in a buffer of faux sadness, guilt and impressive forgetfulness that you then dump on your DDs doorstep - if you're anything like my mum that is. Give a proper and heartfelt apology and really take on board what she is saying or has said to you.
