It is so stressful. I got a local Air B and B and went there first so I didn’t have the hassle of needing to rent somewhere and him find out, and also set up utility bills in my own name and place. It was all too overwhelming. So I booked an Air B n B to go to straight after I told him, and I stayed unit for a month while I got a rental sorted and paperwork filed with an attorney. This way you can go back and get furniture when you are ready and feeling less overwhelmed. Do it in stages if you need to and ask him not to be there. Just get yourself somewhere ti stay that is safe.
