Vent away. Divorce comes with a lot of anxiety. My advise would be to rent a storage shed (pay for one month), put his stuff in it, and notify him that is where it is and he will either need to pay the next bill or get it out of storage. Done and well worth one month of storage fee I would say.
I would be cautious about living w/the inlaws, and very cautious in him getting his hands on your emergency fund. A free consultation with an attorney is definitely in order.
