This isn't really an AIBU more of a WWYD.
To cut a very long story short, my parents have never had a good marriage. There were always arguments in our house, my whole childhood has been marred by their inability to get along. They are very different people and should never have married.
They stayed together for the sake of us (what a f**king joke). All I can remember all my life is tension in the house. Every occasion is ruined by them either not speaking to each other or sniping at each other.
They are both mid 70's now and things are worse than ever.
My mother is so bitter over her ruined life, she is a very negative person, she hates getting older and laments her lost opportunities for an exciting life which she totally blames on my dad.
My dad is pretty useless, never really involved in our lives growing up, he is of the generation that minding children is women's work. He drinks too much and never wants to go anywhere.
They are both as bad as each other and have both contributed to their miserable existences.
That being said my mam has been, and is, very good to me and my family, she is very generous and is always there for us. My dad had issues in his childhood that has affected his ability to be a good dad and father and I don't hold this against him. He loves me a lot and he is trying harder to have a good relationship with me now.
The real issue for me is that they don't have an outlet for their bitterness towards each other and so both direct it towards me. They are really struggling to live together. My dad has cancer and my mam has no compassion towards him. She goes on about her health issues and ignores him. If he tells me he has an issue she will tell me later that he is exaggerating it.
As they are getting older my dad is less able for the aggravation and wants a quieter life and it is like my mam is getting more and more bitter as they age and she is upping the ante.
For example this is what happened today: my mam had to book a GP appt for dad for this week. She did it but he said she wouldn't tell him what day/time it was at. He asked her but she wouldn't speak to him. I had to call her to find out and ring him back with the information.
She gets bitter as he cant make an appt himself so she withholds the information to have power over him, he cant see she is fed up with him being useless and not able to do anything for himself.
I feel sorry for both of them as they are genuinely miserable. They are at an age when they should be avoiding upset like this. My mam is very controlling of dad in the house, she complains when he lights a fire, she complains when he watches tv, she complains if he gets a phonecall. He has no comfort in his own home.
On the other hand, dad would drink and smoke all their money so mam is responsible for all the money/bills/organizing insurance, etc which fuels her bitterness.
I am honestly emotionally exhausted by it all. I have raised it with them and stopped calling over (before covid) for a few weeks as I told them I couldnt bear their behaviour. They did make changes but they soon slipped back into old ways.
I feel guilty reducing contact as both are lonely.
Its really dragging me down, I feel very upset by it everyday. I cry frequently throughout the week about it.
I have an occasional nice visit with them where they dont make snide remarks but they are few and far between.
I have considered professional help to deal with this as during the really bad times I wish one of them would just die as it would be the only way to stop what is happening.
