Due to housing issues (long story) I'm having to spend longer than planned at my parents for Xmas (usually I spend a week or less, I'm there for 3 weeks now).
They have repeatedly said down the years that I am welcome to visit and stay any time, that I can move back in if I want to to save money etc etc. When I was out of work for a bit during lockdown they almost insisted that I come back (I didn't). They have plenty of money and a big house, so I am hardly imposing - I just sit quietly doing my work. However being here I do not feel particularly welcome at all.
They have spent their lives ignoring their numerous personal, psychological and marital problems. The atmosphere growing up was often stifling and I never felt comfortable reaching out to them, even over minor things like learning to shave (I taught myself). Their attitude is 'you had a roof over your head and food on the table - what more do you expect'? If now and again they felt guilty they would chuck cash at me or buy me an expensive toy etc. All of their siblings/parents are/were messed up in some way - alcoholism, depressed, anger problems.
Sadly they have seriously declined since retiring 5 years ago. My dad has spun off into a depressed funk, says very little, and just mopes about the house all day doing nothing. My mother has OCD (possibly diagnosed autism/aspergers) and dealing with her rigidity is draining. If I so much a spill a few toast crumbs she flies into a rage. If I go out for a walk she insists on knowing where I'm going and when I'll be back. She has zero notion of the effect of her actions on others, including my dad who just sits their and takes it (has for years), occasionally grumbling to himself in resentment, or attempting to placate her. Neither of them go out that often, have any friends, or hobbies other than watching TV. They both seem resigned to each and their situation.
I have tried repeatedly down the years to shift from a parent-child relationship to an adult-adult one. They are simply incapable of making that transition, except perhaps if I do a flying visit for a day. I buy food for the house, have offered to help clean, cook meals, contribute to the bills etc. I make numerous suggestions about places we could go, restaurants we could try etc. etc. They just dismiss it out of hand, moan that I've bought the wrong items, that I'd make a mess if I cooked.
Any advice as to how to stay sane for the next 3 weeks?
