Actually, don't leave the house at all. Women always try to pull that stunt. Judge won't give the house to one parent at a temporary hearing. Plus, they you are still under one family housing unit's expenses and not two, keeping the need for child support lower, and eliminates alimony.
Don't let her goat you into an esculated. Remember, Iowa is a one party consent recording state. Keep a journal (don't keep it at home or your car) of what parenting you are doing every day vs. her. Don't give up. I've won plenty of custody cases for fathers that didn't think they had a chance. If they listened to what I told them to do, I promised them things would go better for them. Usually, one parent goes off the deepend, starts hanging out the bars, has a significant other that you are not aware of. Let her do that. It destroys her case. Sometime when she is not home; video record all the possessions of worth in the house, in case they start going missing. Basicallly, your life has to completely resolve around the children until this matter is resolved. No social life.
