My father was wealthy, he was also an addict (drink and drugs). My DM left him when I was 2 (when he puked in my potty after a batch of bad heroin, I kid you not).
Because he was wealthy he was 'above the law' (didn't get involved with petty criminality, just stayed in one of his houses getting wrecked), he also avoided mental health professionals (he was definitely mentally ill by the end).
My father didn't pay a penny towards my upkeep as a child (he used to blackmail my mum by saying he'd share secrets about her if she pushed for any money - I only learned this as an adult).
I saw him infrequently as a child, he'd often not turn up to pick me up, or leave me with strange people while he smoked opium (again, I kid you not).
I didn't see him for the last 9 years of his life.
He died in 2011. He left his entire estate to my half-brother (10 years younger, child of his most recent wife).
When he died he made me the executor of his will, so I organised probate etc. for SB. It was a large and complex estate. SB did nothing to help, in fact obstructed where possible.
DM and probate solicitor suggested I contest the Will, I didn't as I felt like it was his to do what he wished with and I didn't want to upset SB who'd lost his father (and hero worshiped him).
Even to this day, I'm resentful, I have no relationship with SB anymore. I just know that if the opposite had happened, I'd have given SB a little cut, just enough to mean he didn't have to scrimp and could put a deposit on a house.
AIBU?
