Husband rushing into divorce, help

He asked me for a divorce 4 weeks ago today, came completely out of the blue for me. He moved out of our shared home voluntarily and into his campervan and I’ve seen him a few times since and he told me how great it was going for him with no responsibilities 🙄.

The last 4 weeks have been hell on earth for me, barely eating, barely sleeping and just trying to get through the day. He came in on Monday morning just over 3 weeks since he asked for a divorce and demanded that his housing situation be sorted, he was talking about meetings with mortgage advisors and solicitors, told me he’d be buying me out the house, told me he wanted to keep my car, asked me several times how much money I wanted out the house, when I said I’d not be making a decision with legal advice, he flipped his temper and said he was moving back in. I kept calm and said okay, I can’t stop you doing that.

I haven’t seen/ had any contact with him since then and I’ve been out of my mind with stress/ worry. I’m not in the right headspace to be making these massive decisions right now, I’ve barely got my head around the whole thing. I don’t want to have to rush into anything. I’ve got an appointment with a solicitor next week but it just feels like he’s trying to push me out as quickly as possible. What can I do!
