I’m sorry to hear that. I’d talk to him for you if I could.

What happens when you try to talk to him? What did he need your phone for? Or was it just to bully you? Maybe he has difficulties expressing his needs.

Have you considered learning self defense or finding friends to help?

It’s really frustrating when adults don’t help. It sucks that you have to help yourself. You should be able to feel safe and not have to worry about this.

Try relating to your opponent first. Show respect and listen carefully. They might be in a lot of pain and no one is there for them. It’s hard and it will test your patience. Think of it like slowing down a ball of anger rolling down a hill. It’ll just keep going faster and faster until one of you decides to slow it down.

But after you’ve done that, you should not tolerate someone who keeps ignoring your boundaries, and make a plan to handle the problem. Stay calm inside and don’t hesitate your decisions, and fully commit to your actions.

You should sell the house first, establish dominance.

(No but seriously, listen to everybody else :)

How old is your brother? How old are you? This sounds like a troll post showing the overreaction of an online audience to recommend the most extreme response because some vital details are missing.

The cops are unlikely to help you, wherever you are.

Instead, try social services, or a domestic abuse charity, they will be significantly more sympathetic and could potentially offer you support, or at least tools to try and deal with this situation.

The other thing is to protect yourself, go no contact or at least reduce it. It sounds from your short post that you are an adult and live in your own property - don’t let him in. If he has a key - change the locks. If he tries to break in then the police might help, try and gather as much evidence as you can (like a camera doorbell or other recording). Don’t answer any of his communication, if you can, block/delete him from all of your devices and social media. Personally, I would apply the same to your mother, that’s up to you, but it sounds like she’s at the very least enabling him, so isn’t looking out for your best interests, and you need to ask yourself if those are the kind of people you want in your life.

Life is too short to hang on to toxic people who harm us in the hope that they might change. Being related doesn’t make them worthy of your time energy or love. If they do eventually regret their actions and want to apologise and try to make amends, you can let them, or you can choose not to, both are valid.

Take care.
