Mine is my father.
I finally started to call him out on the years of domestic violence my mum had suffered (and I had witnessed) when I was 17. I was encouraging my mum to file for divorce. He punished me by timing a suicide attempt for when I got home from college, and making me witness him overdosing on pills while I called the ambulance. I struggled for years with PTSD symptoms and it also began the conditioning into me feeling that I was responsible for his life/death which has been a huge burden.
While sectioned for the overdose he met a vulnerable woman and moved straight into her council flat and got his name added to the tenancy. Wined and dined her family members and made them think he was great. She suffered 8 years of domestic violence all told and when her son and I found out about it he made a suicide attempt again, this time luckily the ambulance got to him before I did (I had 18 month old DS with me). I became unwell with the PTSD again, plus intrusive thoughts, and driving phobia due to anxiety.
He refused to leave the council flat so the lady left to live with her son, shortly after she took her own life. I now truly believe (post me having counselling) that he targeted her in order to bully her out of the flat.
One particular episode was where I was called to deal with a domestic incident at the flat while heavily pregnant and unwell (overdue) with my first baby - he got us over there by his tried and tested suicide threats.
Around this time it emerged that the lady was suffering from paranoid schizophrenia and had actually committed infanticide during one of many episodes of psychosis, my father had kept this a secret from my husband and I (even though she had access to our young son). More frighteningly he was encouraging her to stop taking her medication as prescribed. This was part of his abuse and gaslighting.
He blamed his behaviour on drink and told me he had quit, but promptly started abusing prescription painkillers.
Has never been happy for me, no matter what my good news (job, pregnancy etc) is he always thinks it's bad news.
Ignored me for weeks on end as a teenager when the rock band I was in got offered a small record deal and tours.
Cried when I told him DH and I were eloping. Cried when I told him we weren't naming DS after him.
Used coercion and suicide threats so I got him illegal substances
Tried many times to get us to leave the DC with the weird old man next door to my father who according to dad 'has done something bad in the past' and is estranged from his whole family
When in hospital with a broken ankle he made up a lot of lies that the docs weren't coming to see him, that they were sending him home with an unsealed ankle - all found out to be lies.
He purposely shit himself in the chair in the hospital and then screamed at the nurses that they were ignoring the bell (he never rang the bell, I was there)
Used coercion to get me to sneak medication into the hospital - I was like a robot, I just did his bidding
When I had a breakdown and was diagnosed with PTSD (I could not function for weeks and was seriously considering doing a runner and becoming a missing person, I couldn't even get out of bed during my breakdown let alone skivvy about for him) he discarded me, sent me a text that it was time I knew the truth - my mum had wanted him to sexually abuse me when I was a child. Then texted my husband immediately after saying I was mad, unhinged and couldn't cope with my job.
Oh, and he started threatening suicide in front of my DCs age 11 and 9. After he'd bought them gold sovereigns worth ££££
Think he's actually a psychopath! I'm 7 months NC now and healing/grieving.
