No you have not been seperated at ALL. In order to be seperated in NC you must live in seperate addresses. Differant parts of the same house does not count. You do not have to file papers to seperate; one of you just has to move out. Since neither of you wants to walk away from your child (good) then you could look into buying townhouses right next to each other (just a thought) That wall and mailing address would be enough.
