Go back to police station and talk to a supervisor. Bring evidence that it is our house too. You want access to your house with an officer as it is your right.
BUT, if there are no kids, this is headed for a divorce. Get a police report that you tried to go back home and she is not allowing you. File for divorce and be done.
Close all accounts in your name (credit cards, utilities, bank accounts). Call them all , see if they will take your name off card, if not tell them to close the account and send you a final bill. You will deal with those in divorce court.
If you have any savings account/checking account take out half, take your name off. Open new accounts in your name. If she does not let you live in house, text her that the bills in your name has been closed.
Talk to a lawyer about sending an official letter to her that since she has not allowed you back in the home, that all bills from XX date will be her responsibility.
