Hoping there are some people from the stately homes threads around. I didn't want to post on them as I don't think I come from an abusive family, but feel like I need an outsiders perspective on this and advice on how to go forward.
I'll try my best to keep it to the point.
Me and dm have always had a bit of a fraught relationship, sometimes worse than others and periods where its all ok.
Growing up I was eldest sibling of 2, dsis was born with a chronic health condition diagnosed when she was 3, dsis and I were and are very close. Childhood involved a lot of hospital visits for her, surgeries etc. I used to wake up in the night hearing her screaming in pain, mum and dad would bundle us into the car dropping me off at the neighbours, so they could take her to hospital. A lot of reflecting had made me realise I never really understood what was going on as they never explained and I'd be scared and not knowing when they were coming back for me. Obviously there was a lot of focus on dsis which she absolutely needed and I'd never resent.
Fast forward to teen years and I went off the rails, not going to school lessons, drinking & smoking, mostly the usual angry teen type stuff. My father's reaction to my behaviour usually involved smacking, losing his temper etc. I can see that they tried at times to understand why I was acting out, I vaguely remember having an appointment with a councellor.
When I turned 16, my father told me to get out of their house, I was destroying their family and not welcome anymore. I moved out and sofa surfed for around a year. I was in a council b&b room after that. My mum and I had sporadic contact at that time, my father didn't know at the time she was contacting me.
In my 20s my father and I did a lot of soul searching and talking, apologies on both sides. The next few years we were all fine, family dinners etc all the usual stuff. I'd go as far as to say we got on great. They helped me out with a deposit for my first flat.
A couple of years ago my mum got ill, she nearly died and had to have life saving surgery and she'll be on medications for the rest of her life. During this time my dad and I pulled together, supporting each other and mum as dsis lives on the other side of the world and couldn't be here. Was a horribly traumatic time and I found out I was pregnant with ds when she was first taken into hospital.
This is where things get complicated. Mum is now a very anxious person, she is extremely negative and seems to be bitter about what happened to her and how her life has changed, dsis and I agree this is completely normal and she possibly needs to have therapy to deal with what happened to her. She absolutely won't engage, and has cut off multiple friends for perceived slights, she also has no contact with her mother or siblings (before the health issues) again never really clear why. Dad has agreed with dsis and I but won't speak up, and takes barrages of abuse from her weekly but doesn't want to rock the boat. We all walk on eggshells around her for fear of upsetting her.
The past year there have been a few surface type arguments between mum and I, usually due to her disagreeing with how I live my life. She has made comments about how both dh and I have to work full time, it's bad for my ds, why didn't I save up before I had him to be a sahm (like she was) how she is ill and doesn't need to be worrying about me - I don't give her reason to! She badmouths me to my dsis constantly. My dad agrees something isn't right with her and she seems to project it onto me, but he won't say anything and he now won't engage with me. It all came to a head this weekend at my ds birthday where there was an obvious atmosphere between parents and I. I talked to mum about it yesterday and she told me how my father can't forgive me for how I've treated her this last few months (I backed off and didn't see them much due to the arguments and the hurtful things she said, including how I dont consider my ds in my career choice - I started my own business this year in order to try to have a better work/life balance as the country we live in jobs are scarce and the hours in tourism ridiculous) so anyway had thrown at me how they can't forgive me, all I do is upset her etc etc.
Her parting line to me as she slammed out of my house was that she could die tomorrow and wouldn't I be sorry then - how she had awful blood results recently and I should be careful. Her hospital results at every check up are good, she even sent the last results to my dsis (works in medicine) and sent us pics of her and my dad toasting with champagne to her good results.
I called her yesterday evening worried sick, for her to completely deny she said it, telling me I'm crazy and putting words into her mouth.
I'm devastated, it feels like she inherently dislikes me. Messages between dad and my dsis where he has said he doesn't see it getting resolved - my 'behaviour' just upsets her and she was a nicer person to be around when we were barely in contact.
I truly don't understand what I have done for her to have this huge resentment towards me, I can barely think straight today and am just at a complete loss.
Sorry its so long, there is probably a lot of relevant I've missed but this is the gist of it.
