Get back in the house. She is attempting to demonstrate that you abandoned the home. She is also attempting to show down the road a status quo of her providing for the children in the home while you are not there. Therefore, when this goes to divorce she will get the home and the children (use and possession). My advice to you is to have the police escort you to the house. Otherwise she will accuse you of beating her and then she will seek an emergency ex parte protective order. Make sure you have a witness around because she will claim abuse; I guarantee it. You will be forced out, forced to pay the mortgage, forced to sleep on a buddy's couch, you will lose the house, you will lose the children.
Get back to the house ASAP.
