You can't keep things amicable with a lion that wants to eat you, unfortunately.
It is going to get messy one way or another so you need to be prepared to take action.
Assuming his name isn't on the property, you can simply have the locks changed when he is out at work and drop his stuff round with his family.
Or have a relative round and tell him he is to leave today. If he kicks off, call the police.
Showing them kindness or compromise is taken as weakness. They attack weakness. Theyve trained you to try to appease them for a quiet life. But you have to resist that and do the uncomfortable things that need done to get them out.
Best thing you can do is take action and show them you have support and aren't afraid to call the police on them etc.
Do not get sucked into merry go round conversations about why its over. Just 'because I'm done'. They'll try give it whyyyyy and all that shit. Just "Because I'm done'. They might hit you with 'you aren't going to fight for us?' Or some similar guilt trip. Just 'nope'. Dont be drawn into it.
Their objective is to exhaust you.
That's why you don't give them time around you to do so. Fuck week, he leaves today.
He doesn't have anywhere else to go? His.fucking.problem. He shouldn't abuse women. If he didn't, he could be given time to leave. But he does. So - fuck.him. He goes today or the police are called.
If his name is on the lease or house thrn that may change things somewhat. See a solicitor. But, you'd like wise to be out of there yourself ASAP if you can afford to.
