Usually they come back for second attempt, if they didn't get much the first time. You and your husband should prepare something or move out for a few months. The law in this country protects criminals only.
All thiefs would have a sort of assessment how their vitims would be alike, how much their wealth about, anf if they would resist if the thiefs would be back again. After first stealing, they know your house structure and where things would most likely be placed at. If they think there is no threat for themselves, the chance for them to come back is bigger because they probably can get something more easily than stealing a strange place.
