Name changed as this may be identifying. Apologies for the length of this.
I'm an only child, grew up in another country but moved to the UK at 22 to study and have been living here for the last 15 years. My parents still live in my home country.
Part of my reason for leaving home was to get away from my parents and I've never been able to understand why. I am close to them in that I confide in them and tell them things about my life, no secrets, but I can only cope with speaking to them once every few weeks and seeing them once a year and preferably even lesser than that. But I have very complicated feelings about them and it's only recently I have considered that maybe what I thought was a good childhood was actually a bit messed up. However, I need outside perspective to help me understand why I feel this way.
My parents were/are very doting and made huge sacrifices for my education and future. They are supportive of all I do, affectionate and loving and good, hard working people. However, we had an unusual set up in that my dad quit working when I was a baby to look after me and my mum carried on working in a job where she was out of the country for most of the month. My dad does all the housework, financial planning, organising, driving, cooking etc and did the bulk of the child rearing. My mum helps out a little bit.
From a young age, I remember that my mum had terrible mood swings. One minute she would be excessively loving and sweet (to the point of suffocation, almost like she needed validation from me), the next she'd be hurling abuse, throwing things, and her face would contort in a vicious rage. Most of it directed at my dad but I got a fair amount too. She would also cause huge scenes in public berating me or my dad, storming out, loudly yelling etc - to the point I dreaded going out with her. We always had to walk on egg shells when she was home and I would hide in my room waiting for her to leave. She was extremely anti social and distrusted and disliked absolutely everyone - but in front of people she was charm personified. However, she'd stop me seeing friends or getting close to other members of my dad's family or dating - because she'd tell me they weren't good people. As a result we all led a very isolated life. My dad is a much more social person but ended up cutting off all his family and friends to avoid arguments at home.
This has gotten worse as an adult and after she retired. I know she is deeply unhappy with her life and has always been (no idea why) but refused to do anything to change. What was just mood swings is a permanent rage filled existence and an extreme paranoia that everyone is out to get her. The result of her behaviour means I now realise that my dad turned to me for emotional support from childhood and even though I love and respect him, it makes me feel a bit weird. As an example, I used to have to share a bed with him till I was 12/13 despite having my own room (nothing untoward ever happened) but that memory makes me feel a bit ick now. After I moved away, when they'd come to visit he would get angry if I asked for how long and expect to just stay as long as he wanted - in my tiny studio flat. This would often be almost 2 months until I would have to forcibly ask him to leave. His communications with me are very OTT with emotional and flowery language, it makes me feel uncomfortable - it seems less like father/daughter and more like how I am with my DP if that makes sense. I've been suggesting they divorce for years but they're almost 70 now and neither will do it - it's not common in our country.
This came to a head this Xmas when I went home for a few weeks. My mother's behaviour was awful, she raged and abused me most of it (So loud that neighbours can hear), went on these long racist rants (including against my dad's community), was insulting about my friends, doesn't leave the house or look after her health (she's losing teeth from poor hygiene and won't do anything to sort them), she physically threatened me in an argument and then hit my dad. I think she may be mentally ill, definitely depressed. But refuses to get help and thinks all psychiatrists are a waste of space. I left the next day telling my dad I couldn't come back as it was affecting my mental health living in this environment. He cried and made me promise to come back and to just accept my mother's behaviour like he has. He said I was the only person in his life he could talk to. Since I've been home, he messages and calls in that same emotionally OTT/martyred way where I feel like I'm his wife or his mother, not his daughter.
I am considering cutting contact with my mum until she gets help. It breaks my heart because she made a lot of sacrifices to give me a good life, and at her best was an amazing, bright, beautiful woman. But am also considering going LC with my dad because our interactions make me feel uncomfortable and I don't know why. I'm questioning now whether my relationship with him is actually unhealthy, because he sees me as a replacement for my mother. or I'm being unfair. So need advice on the best way to manage this, also as they have alienated themselves from other family/friends.
