Just that really. He will use it whenever he feels like it and doesn't feel the need to even tell me he'll just do it and I either notice its not outside our house or I'll see him pull up in it. When I ask why he says you weren't using it or I thought I'd save petrol or I thought it could do with a run out as I'm working from home now. I used to have just one key and no spare. Then he got a spare key cut which I was grateful for at the time however hes recently cut himself a third key which I didn't know about which he's put on his own key ringing with his own car keys. Ive told him that taking my car without even asking or mentioning it is taking without consent. He told me Dont be so ridiculous.
He also took its upon himself to get my car mot ready this weekend. Secretly and again without asking.
