My father in law refuses to listen to our requests not to work in/on our house during weekdays.
So, there's a bit of a backstory here. We bought a house 8 months ago, started renovating and during that period we were invited to live at my in-laws. My father in law is already retired and is bored all day. He has the key to our house in case of emergencies etc. When we didn't live in the house yet he was free to work on things whenever he liked. 2 months ago we moved in, but he still comes and goes whenever he likes.
We talked about him discussing coming over first, but he gets angry whenever we try. He throws the 'You should be thankful I'm helping' argument everywhere. He now sends a message to his son (my partner) only, but he's often working or can't respond soon enough and then he'll go without having an answer anyway.
This resulted in him showing up in many unfortunate situations. While typing this now I'm working at home due to some circumstances and he just came marching through the door. 'Oh I messaged X but he didn't respond.' and is now working very loud equipment. When I asked him to stop he said it was important he does this today. Perfect working conditions...
Next to this he is quite clumsy when we're not around, perhaps because he is getting old. He has broken or damaged multiple things already.
Every time we discuss this issue it ends in a fight or him being offended. We need his help to finish the house, but we'd prefer he comes here only on the weekends. He says he needs his rest on the weekends so he doesn't want to work then.
Is the only option we have left asking him no to come at all anymore? I'm afraid even asking that will offend him. Normally I'm quite good with turning things my way but however I put it, he finds something to be offended about and will make a whole drama over it.
