Since you had to ask the same question twice, and got the same answers...
may I recommend an appointment with a Criminal Defense Lawyer?
Doubtful significant other will get to stay in the current living situation as (1) Too poor to afford the halloween costume, (2) shoplifted after moving out.
As for the Halloween costume....I'd suggest before trying to be out on ones own again - take a budgeting class and learn financial priorities, how to prepare and live on a budget. Rent, food, staples (deodorant, toothpaste, toilet paper) are the priority. Halloween Costume is a luxury. That along with my previous receommendation.
