If he's been there less than 30 days, trespass him and call the police. If it's been more than 30 day, you'll have to legally evict him.

Has he been like this your whole life or is this new behaviour? If he's been abusing you your whole life then you need to go cold, refuse to engage and start the eviction. It sounds fairly straightforward from everything I've read, just intimidating as all hell. If this is life long treatment then your local Domestic violence support people will be able to help you through it or direct you to people who can help. If this is new behaviour then he needs a full medical. Many things can cause personality changes and they all need checking for. Even something as simple as a bladder infection can have a shocking affect on people. But if you've been taking the brunt of your father's temper for so long it's become perfectly normal to you, then please find your local DV support group. They'll be able to help you. It doesn't matter that you are a guy, doesn't matter that it's your father. They deal with situations like this for a living and a vocation. You are being abused in your own home and you want it to stop. Find the experts and listen to them. Unless you can afford to pay him to just **** off. If so then give him enough to keep him gone for at least 30 days so he's legally 'abandoned' his tenancy, change the locks and call the cops if he shows up demanding to be let back in. You just need him willingly gone long enough to void all his rights. He probably isn't that stupid though, unfortunately. So, Google local support groups, call your local free hospital or pop in to a church, food bank or community centre in your area and ask them for the DV support groups they work with or direct people to. Help out of this is there, you just have to find it. Even if it *is* medical, he's still abusing you and they will still help you. 🫂
