i think availing yourself of the airbnb is a SANE decision!!
however, if you are going to leave the house "to him" for a period of time, consider what ELSE you might wish to have with you, and not accessible to HIM. things you do not want to or cannot afford to lose. consider who NEEDS to know where you are, and who does not.
consider changing passwords. take or secure blank checks to any accounts, extra cards, your passport, etc.
i don't say this to scare you, but only so you plan well and cover your bases.....there are things we NEVER could have imagined THEY could do.....
