If I were you . . . I would take the house, get it finished up, sell it, and get the h_ll out of there. It cannot be healthy for either of you for you to continue to live so close to one another and keeping up the entanglements on some level. Just the fact that you felt compelled to go over there or open your own door says it all. However I know your parents are near and that's a factor so it may not be so easy for you to pick up and go, but I do wish you could.
