Where did you live while separated? Post divorce ?

Filed for divorce a little over a month ago from long time spouse of 12 years. Me 33F filed from STBX 42M. We share multiple school aged children together. We’re currently in house separated right now (I live downstairs, he lives upstairs) in our marital home but I’m not sure how much longer we’ll be able to do this. We’re high conflict but also HCOL area. Wondering where everyone ended up living while going through the divorce ? And then where did you live when it was finalized? I have multiple children and not much family support so it seems options are limited. Living in-house separated is a whole lot cheaper but it seems I am paying for it quite a bit through peace of mind, freedom and mental wellness. Thanks in advance for everyone’s input.
