Rent a storage locker and get everything out of the house quickly. Throw out anything that you both feel ok letting go of, but don’t put much energy into decisions about stuff where you’re not sure. Just chuck it in storage immediately. Now you have an empty house and can move. You also have a monthly storage bill but that’s hopefully a lot less than the rent on the house, and you can take your time getting rid of stuff from storage, or even selling some of it on CL/ebay.
