My father threatens to cut off financial support for my younger siblings because of my choice of partner

Sigh

Where do I begin. So my father just pulled a grenade on me and told me that if I didn’t drop my significant other he would stop financially supporting my siblings. 4 of them are under the age of 16. I’m from a third world country so no one would hold him accountable not even his family.

He has known about her for 2 years but every now and then he tries to push me into a direction that would lead to us breaking up, like joining the army or him funding my education abroad. I know the issue is not really my partner but his control issues. He has successfully wrecked the lives of so many around him and they are in complete submission.

He splurges money on strangers but draws the line on his family. So many flying monkeys my way but they all do as he says because he has supported them financially. I can’t let my partner go, she is my everything. I’ve been given an ultimatum and it comes with a lot of pressure.

My father wants to control everything in my life; who I spend the rest of my life with, what I do for work, what I do and so on. I honestly don’t understand how someone can be this horrible.

I’m honestly at cross roads, the only time I get a good thing and now he wants to take it away from me.
