My dad is an aggressive bully who spends all of his money getting drunk everyday

Maybe this is a Dear Abby kind of post, but I’m just wondering if any GLPrs could tell me if my dad has some sort of personality disorder.

Since as far back as I can remember, he’s been drunk every day. He can - most of the time - be nasty and aggressive, and bullies the hell out of my long suffering mother.

He’s self employed (with a work partner), but is claiming welfare on the side. He gives this welfare money to my mother to “provide” for my other 4 younger siblings, but there’s a catch… this money he gives to her is actually used to provide for him because the money he works for is completely spent on alcohol. Nothing else.

Because he’s so incredibly tight fisted, me and my siblings were bullied because we were obviously “poor”, and had to wear the cheapest / second hand clothing.

If my mother dare ask to lend a tiny amount of money from him to top up gas or electricity, he goes ballistic (even though it’s used to heat him / provide him with food also). When welfare payday comes, he demands this money back.

My mother can’t work because he’s very jealous and paranoid, and forever accuses her of having affairs with other men, consequently threatening to kill her ‘stone dead’.

He shows zero interest in his kids, has never taken them on day out in their lives. His only interest is getting shitfaced drunk every day, then threatening my mother (and his kids).

I had to leave the family home early and get my own flat because as I got older I had to take a stand against him beating, strangling, verbally abusing my mother. I have PTSD from everything that’s happened, but the money I make from my minimum wage job goes to my personal upkeep, and now providing for my mother and siblings.

I’ve provided refuge for them all, but she keeps going back because she’s - strangely terrified of him - thinking she has no rights, and he’ll eventually track her down and kill her.

He’s in mid 50s now… and the irony is, as stingy and tight as he is, he has no money because he selfishly blew everything he earned on alcohol.

But anyway, back to my point… there’s obviously something extremely wrong with this man. He must have an undiagnosed PD of sorts. Do you think he’s a narcissist, psychopath, other?

BTW he’s abandoned kids from previous marriages — each marriage broken up because of his drinking and violence.
