NC for this.
i really feel for you, and I don’t know what the answer is.
However, I do think he is being abusive and you should take this opportunity to try and refuse for him to come home.
I had severe MH issues in my teens and twenties, and to an extent, still do albeit now well managed and with insight.
My mother took a v different approach with me, and whilst I don’t advocate it, there were elements of it that in hindsight did benefit me….
Essentially, from her POV, I turned 18 and as an adult not in education (MH prevented me from finishing school) , I was considered responsible for myself. This meant that i had to seek alternative housing and financial support. She was happy to advise me of the routes - which would have been b and b if I waited to be turfed out. But if i got up and out every day and went to GP, mental health workers, DHSS, homeless persons unit (alone) - and argued my case, I could stay pending being offered supported housing . If I didn’t, I could present as homeless and have b and b or go on the streets.
I didn’t threaten suicide but had had many previous attempts and hospitalisations. I also self harmed to the extent that stitches were often needed, so there were records to help access supported housing.
Whilst I was with her , she didn’t want me to be too comfortable! It was pre internet. I was only allowed to turn on the tv in the evening. No heating in the day. Did my own laundry and most food. Not allowed to slob around - up and dressed and out the house. No snacks at home - so lots of incentives to sort benefits. She would give advice - about benefits, where to buy cheap food, cooking - and later on re voluntary work and interview guidance - but only if asked.
No doubt she was terrified I’d kill myself. She said once that she would never get over it if I succeeded, but she could not stop me and it would be my decision and she wouldn’t be to blame.
I don’t know really. It was tough. I felt very uncared for . But it did kick me - and I was eventually housed in a MH house and gradually moved forward and am now a uni educated professional, married with kids. We now know that I am AudADHD as are my children, but as we know, girls and women are so good at masking!
She did hold onto her need to have her own life and that I needed to take responsibility for mine and sink or swim. If I has a comfy room, TV, meals and laundry being done for me, maybe I’d still be there. There were definitely weeks at a time I didn’t shower/ wash / eat etc - but you do end up sorting it out when your housemates swear at you and tell you that you reek …..
