I'm in, too.
In the long term... oh, where to start?! She told me when I was maybe 5 or 6 that - in NI - she'd taken tablets "to get rid of" me. She broke my nose when I was... a year old-ish. She told me, in graphic detail, when I was 4 that my father had had an affair with a colleague and that "the only reason [she] went back" was because of [me]". She hit me in the face with a shoe when I was 13, then lied about the black eye when my grandmother questioned her about it. When I was being sexually abused (by a family member as a 7 year old) and badly bullied as a 14 year old... she told me it was my fault. She didn't notice for 7 months when I moved out, aged 15, but then, she didn't notice that I had an eating disorder from the time I was a year old until my DS was about 2, either... When my daughter was born, we were living with her again, and she dragged me to a solicitors 5 days post-partum (with a child who'd effectively died in my arms 2 days prior) in an attempt to get parental responsibility for my daughter (the solicitor took one look at me, one look at her, and said "no"... but she's never actually forgiven me for that!). She took it upon herself to choose my daughter's first school, which was 3 miles from our home but 2 minutes walk from hers, whilst I was at university an hour's drive away - then cancelled her nursery place (I honestly think that this was her attempt to get me to quit uni... which I didn't do. I simply... juggled and ended up owing my daughter's godparents a lot of favours!). She still undermines me when it comes to my daughter, 20 years later.
When I told her that I was pregnant with my DS (11), she said "I didn't even know you were still having sex!"... I was 28 years old and I'd been with my ex-P since we were 14, on and off, by that point. She then insisted on having a "chat" with said ex-P... during which she got her knickers in a knot because he wouldn't allow her to bully him into allowing her to do whatever she wanted. Prior to this "chat", when I lost my DS' twin in the first trimester, she said "oh, that's how all my miscarriages started..." - and took my daughter away for 3 days, over the Easter weekend, leaving me completely alone and bedridden... because my ex was at a wedding and I was too terrified to move in case I lost my DS, too. She bullied me into having her in the delivery room, then mocked me in front of the midwives (who were all great). She bullied me about picking my DS up every time he cried. She bullied me about wanting to breastfeed... because she "couldn't". She bullied me about "allowing" a relationship between my DS and his paternal family when we broke up 18 months later.
She bullied me a week and a day ago when my daughter left me for dead, and I refused to have her back in the house... because apparently that makes me a bad mother!!!
15 years ago, when my step-grandparent died and we'd arrived for the funeral, she attempted to bully my grieving Gran into going and buying her the milk she wanted... and then couldn't understand why everyone was looking at her as though she were insane (I can still see/hear her clapping her hands in an "oh, well, this won't do... where's the milk for my tea?!" sort of way).
When my dog was put to sleep when I was 18, she muscled her way on in to her head, and I was left by the tail (my father was there, too) watching my childhood friend trying, desperately, to get to me... this, after she'd taken said dog to the RSPCA because she was "too dirty" in an effort to get rid of her as a pup... and spending the next 15 years moaning about how my dog "looked at [her] funny!".
She doesn't like the fact that I won't allow her to turn up on my doorstep as and when it suits her. She doesn't like the fact that I won't have anything to do with her mother (who is worse than she is). She doesn't like the fact that I have 'A'-levels, let alone a PhD... because she dropped out during her 'A'-levels and no one is allowed to be above her in any way, shape, or form. She doesn't like the fact that I wouldn't let her convince my daughter to drop out of college on a whim. She doesn't like the fact that I encouraged my daughter to go to uni ("it's only an art school..." apparently). She doesn't like the fact that I am my daughter's next-of-kin, not her. She doesn't like the fact that my son has her measure. She doesn't like the fact that I won't have anything to do with her Golden Child son, who tried to kill me when I was 5 and he was 15... but that I have a close relationship with the other scapegoat in the family. She doesn't like the fact that my children have another set of grandparents, full stop. She hates that I had a close relationship with her father and my father's parents.
She loathes that I'm more maternal than she's ever been (although that wouldn't be hard...). That was her big sneer until my DS was about 2 years old. "Oh, you're too maternal...". Uh-huh. Apparently not ignoring him every time he cried/cuddling him/interacting with him... was being too maternal. She doesn't like the fact that I have a close relationship with my father's family, but not with hers...
Oh, and she hates that I have no problem in cutting people out of my life if they're toxic.
