Sorry if this is long. I have namechanged.
I'll start by saying that my father is a very angry, controlling, moody man. My childhood was spent often in a state of fear because of his moods. My mum trod on eggshells but has always gone along with what he says, she wouldn't dare not do as he says (but she has her own toxic personality too). My younger sister was the favourite, I wasn't, and I spent a miserable childhood and teenager-hood, getting regularly smacked, told off for everything and with my dad sulking for days over some small or imagined misendeavour. I never really got a chance to develop my own personality.
At 21 I left home and got married to my first husband, who was very abusive towards me. My parents witnessed him being abusive but effectively condoned his behaviour. They wouldn't let me go back and live at home even though he was behaving terribly in front of DD1, and tried to blame me, or tried to stay neutral. Once he was awful to me in front of them and I answered him back and it ended up with my parents shouting at me, so all 3 of them all ganged up on me!!
Ended my marriage and was on my own with DD1, then met my now-DH and we have 2 children of our own who are aged 7 and 5. DD1 is now 14. Since DD1 was born, my parents have basically ignored me, and undermined me with her constantly. If I ever told her off when she was little or even played with her they'd start huffing and shouting at me. They did things with her behind my back, such as started her on solids without my knowledge. The undermining has gone on for years and years. Yet on the other hand they are also very short tempered and have no patience with the kids. They want to just see the kids to suit them and to 'show off' their grandchildren. My dad sometimes really loses his rag with them, like he did with me, over something very very minor or imagined.
Other things my mum has done in recent years:
Still favours my sister. Does all sorts of things for my sister such as kitting her kids out with clothes, looking after her kids, looking after my sister if she's ill. Won't do any of that for me, even when I had a severe chest infection. My mum gets huffy if I'm ever ill.
DD1 has gone to stay with her dad as she is having a rebellious phase and I've found out that my mum engineered it with DD, and advised her to do it. My mum makes it clear she thinks I'm a bad mum (I'm not at all), and she always has a disapproving air about her. DD1 isn't really speaking to me but is in constant contact with my mum but my mum says she's 'not getting involved' and won't tell me anything DD says, and doesn't care that it's upset me the way DD is treating DH and I.
Is very pedantic and petulant with me. She'll say the sky is blue, I'll agree with her, then she's snap and say it's pink! She wants me to agree with her all the time, has no interest in my life at all, and is so uptight and won't have a joke at all,ever. She starts randomly shouting at me for no reason, if I don't agree with her over anything.
They have relied upon me not ever voicing my opinion. I dared to do so in the summer and now my dad isn't talking to me (no loss there!) but my mum keeps coming round and carrying on with her old ways, undermining me, not listening to me, and not giving a toss about me at all. She never approves of anything I do, ever, and never compliments me.
I feel like telling her not to come round anymore. I know she will never change. I think she, along with my ex husband (who is an arse) have ruined DD's relationship with DH and I, and I don't want her to do that with my younger children.
