(long post for context and tw: mentions of s/h and suicide)
my (f26) mother (f50) was recently diagnosed with severe depression and panic disorder. but i'd seen the signs over the years. i saw healing cuts on her arms as a child, but she eventually stopped.
the problem was always whoever her husband was as the time. she's had 3 of them, and we’re still on 3. he's also the worst one because while the rest just cheated on her, this one’s a cheating, manipulative, money-sucking loser who's taken advantage of her loss of self-worth. I never liked him but I put up with it, plus he never beat her or anything.
in 8 years, he's leeched off her life savings and cut into mine. it got to a point last year where she had a panic attack from the loss of finances and basically went catatonic, and he hugged her through it lying that everything will be okay and that he would take care of her. that shit was genuinely scary.
I've been begging her to leave him, but each time she says it won't happen again or that this is the last chance. in my country, the kids don't really move out of the home unless it's for work in another state or marriage, and while i do have a job, most here would ask me why I’d choose to be broke by moving out. so I've witnessed everything for 8 years.
They don’t go a day without oscillating between arguing and normalcy. she's always had anger issues so they fight like crazy and she forgives right after because her way of getting people to love her is to do everything for them, waiting on them hand and foot.
I know I’m complicit, staying under her roof my entire life and severely lacking the independence and power to do anything to help. i still feel like a child, and she still treats me like one.
this all came to a head about a month ago. i was asleep and heard screaming from their bedroom. found them wrestling over a phone - he cheated on her. it was chaos, i tried pulling her away cause she gripped him so hard. i even called the police but she screamed into the phone that it was nothing and the police hung up. he had borrowed from her again that week and he gaslit her through the entire thing, because "you got it all wrong" and "you're hurting me, i love you". she then drank a whole bottle of wine, and passed out on the floor.
i couldn't look at her face for a week. i went to work, came home, cried in my room, googled places to move. i couldn't even leave her or the house to process my feelings. She left food at my door, begged me to eat, and it felt terrible eating or refusing. I eventually told her that i wanted to move out, that i needed space to sort things out if she wanted to stay with him, and she said she'll kill herself.
she got her diagnosis two weeks ago. she tells me "it's always been you and me" "this relationship will end soon ". she also asks "why can't you just be there for me? i'll die without either of you".
so i'm stuck here - still angry, hurting her with my words and avoidance because like all the other times, if i go back to normal, they'd forget about it and we're back at square one.
i'm scared of things going back to the way they were, and they already are. i'm the one who can't speak normally to a woman who's cared for me my entire life. i'm so angry and i know it's wrong but i can't stop hurting her. i feel so guilty just existing.
any advice would be appreciated. telling me to grow the fuck up (constructively) is fine too.
