Op please listen…not to be over dramatic but this situation is making my spidery senses feel worried for you.
He’s a grown man who by the sound of it is being very abusive to you or he is having some sort of mental breakdown which is making him abusive.
You are being abused in your own home.
You need to draw an end to this. Right now. It doesn’t matter if his abusive behaviour started 2 days, 2 weeks, 2 months, or 2 years after he moved in. His behaviour isn’t acceptable and I understand this is painful because you are devastated but you need to instigate a boundary. A boundary is nothing about the other person btw. It is all about what YOU will tolerate or not.
Where he goes is not your responsibility. He sold his own home willingly you didn’t coerce him in to doing that.
Get back on the phone to that support line and ask for more urgent help.
Go to a solicitor and see what your position is financially etc and if you can legally change the locks.
Gather together any documentation you may need about any joint assets, any joint bank accounts, mortgage, insurance, etc.

I don’t like the sound of this at all. He is either calculating and deliberately creating a scenario whereby he is trying to get you to leave your own home for his own financial benefit, or he is doing the very things he is falsely accusing you of doing and wants the blame to rest with you, or he realises he has made a big mistake in moving in and wants to make it all your fault and not accept any personal responsibility for his actions.
Do you have any male friends or family members or work colleagues who are preferably physically fit? If so, once you have legal advice, you need to ask him to leave in the presence of other men.
Don’t feel embarrassed. Any balanced decent man faced with a relationship difficulty would not be up for the third night running at 4 am having ripped you apart in an argument. They would be speaking to you decently and calmly about any issue they have during daylight hours. And if they had a real issue they would be the one offering to go to a hotel and instigating a proper discussion after a few days of separation. And all of your discussions would be respectful.
Does your dp not work? How come he is able to be up at 4 am causing this havoc?
