I agree with what some others have said that if it's not going to hurt you legally (and really, I don't know why it would) it might be good for you to go stay somewhere else else. It will be very hard to fight the impending war against your husband if you're living in the same space. He clearly knows exactly how to tear you down and his attempts at it are just going to get worse as the divorce proceeds.

I also think it's not a bad idea to look for a new house. If your parents are willing to buy your current one surely they would help you look for a new one. Living in that house with your husband now will make the divorce much uglier because neither of you will have your own space (even if rooms are divided you will still see each other in passing) and after a divorce all the memories held in the house wil be tainted. I couldn't live in the house I shared with my ex after our divorced. We'd lived there 10 years and the smallest things would make me angry or upset after the divorce.

Sorry you are going through this.
