So, for some back story, my mother is in her mid 70s (I'm 40) and it's very difficult for both my brother (43) and I to want to spend time with her. She's regularly very unhappy both because of her life choices, her weight and she's in chronic pain (peripheral neurapathy). How much of this is her fault, I couldn't exactly say, but she leads an extraordinarily sedantary life with no exercise whatsoever and a poor diet. She's still married to my father. They live in the same house in separate rooms.

She's the type of person who doesn't really understand how to have a conversation without complaining. I've met a few of these in my life, but she's the worst by far. If you ask her how her life is, it's all negative. She begins conversations by complaining about literally anything "this town is going downhill fast" or "this meal isn't worth the price" (and if the meal is good, it's skimping on portion size. There's always something) She never has anything positive or happy to say.

For what it seems like, she's unhappy in her marriage to my father as well. She treats him like shit. She talks to him like he's the help and berates him when he makes any mistakes. She screams at him and calls him an idiot to his face. She's also told him that she wants a divorce on at least 3 occasions. They won't divorce because neither one of them can function alone. So instead they fight constantly (almost every day, but at least 3x a week) and rarely over worth things fighting over; things like the can opener got put in the wrong drawer or something on that level. The fights always escalate to her telling me father he's a lousy useless piece of shit for not paying attention or just being the worst human ever and then it's just an all out screaming match.

She's basically at best a miserable old woman with a terrible personality and has little to no redeeming qualities and if she wasn't my mother, I wouldn't entertain her existence for even a second; but she is my mother and despite everything I'm saying about her, I do love her and every once in awhile when she's pain-free or in a good mood or something, I get roped into doing something with her because I think "maybe this time it will be OK" and every 👏 single 👏 time 👏 she defaults into the person I've described above and I regret getting involved and hate myself for falling it for it again.

In a perfect world, I would rarely if ever see her again, but some little voice in my head tells me I'm a terrible person for even thinking that, let alone doing it.

So I guess I'm just wondering, after vocalizing it to the wilds of the internet, would you agree that walking away is right or do you think I'm an ingrateful asshole that should put up with it for the sake of having a relationship with my mother?
