if some stranger took my stuff out of my house and sold it on face book..I'd be contacting local police about theft issues .
You didn't respond as to how your home was titled ...but it may well be that you own 50% of it ....
it's sure to be a long drawn out battle, me, I'd try to sort out being IN my own home for the duration and if he is more than irate such as making threats to harm you while you are in the house..you might succeed at getting a protection order which keeps him away/out .
if the status quo was you were in there..I'd be real wary of letting him have exclusive use wo input from my attorney.
