When my H left, very unexpectedly, he took the car with him. I didn't feel like arguing with him about it - or talking to him at all, really - so I went out and bought myself a banger the next day. It runs fine for what I need it for, and if it looks like I will be making our separation more permanent, I will get a better one this summer. But a few days after I got it, he wanted to talk to me about the MOT - he'd been online and looked up the registration and wanted to talk to me about not driving the kids around in the car because he didn't like the MOT history, and he wanted to take me off the insurance for his (the family) car he was using for himself, but me still carry on paying the insurance. Even that early on in our situation I could see it was all control, and I told him to get a grip on himself and jog on. Things are obviously much more amicable between us now, but I still treat his car as the family car and arrange to use it if I am going on a longer motorway journey, and he's never been in my car and I reserve the right to have a muddy dog in it without his commentary if I see fit. Independence is a wonderful thing.
