This is going to be a bit complicated - I've migrated here temporarily from the Cockroach cafe as I feel like all I am doing on there is being sad and I'm not being a very supportive forum member.
I grew up in a household with emotional/verbal abuse and coercive control from my stepfather. Thus was directed mostly at my mother but also towards me. He was (and is) mercurial, aggressive, prone to long sulks and cycles of depression/love bombing/threats of suicide. My mother has suffered a very long time. I had a watershed moment with him in my 20's resulting in him mostly leaving me alone. I have always told her she could leave and I would support her.
Due to complex circumstances, my mother and stepfather came to live in a cottage on our land (~20 metres from our house). His health has not been good and he now has dementia, mobility issues, etc. My mother has been his main carer which has been a thankless task. I have been very involved with arranging healthcare and more recently, ordering continence aids, arranging Frailty clinic assessments etc. I have LPA for Health and Finance - foolishly I didn't think I'd need to use them as he is so much older than my mum.
Last week, things reached crisis point. My mum no longer felt safe in the cottage and finally left. This has been really difficult, I am signed off work sick. I have taken over my stepfather's care and am speaking to his GP, psych nurse and social services.
My question is per the title. I am still afraid of this man in some ways. He has shaped my attitude towards men and my instincts in confrontational situations are very flight/fright/freeze based. I have a lovely DH and fantastic DC and I think in my home, the cycle is over, but I need to heal.
The worst part is gaslighted myself that I am overthinking all of it. Sometimes I wish my stepfather would just hit me and I could have him arrested and it would be over.
