Separation Question

Last Fall, my STBX and I made the decision to separate and divorce. She put my things by the door, and I moved out for a few weeks and stayed with friends and family while seeking my own place. When I wasn’t having much luck locating a suitable place, she said that “for strictly financial reasons” I could move back in to get through the holidays, and our lease was up in March so I might as well just wait until then to move into our separate places. We set up two separate bedrooms in the house and I was only there during weeknights. Are we able to use that initial date of separation or do we have to use the date at the end of February when we finally got our own places full-time? Thank you.

You must use the date at the end of February as the date of separation as NC does not recognize constructive separation (living under the same roof, albeit separately).
