If we track back the Quran we are going to find that Allah doesn't detailed some queries because he puts some another auto-answering "if can i say" system in the human soul, it is clearly here that am talking about Al-Fitraa, if a Muslim wife complained about eavesdropping from his husband and the same case touches a non Muslim wife is it going to differ ? i don't think so, because this kind of problems are humanized, it means the Muslim or the non Muslim will going to feel that they have been cheated, it is the same feelings that causes same reactions in the same time andwith all human beings repeatedly, it is not like the standard believing judgments where a non Muslim will not care if it is Hallal or Haram, because they don't believe in what you believe in, so, Allah equipped you with Al-Fitraa that's going to judge without any arguing about Islamic rulings and what wounds Al-Fitraa will not satisfies Allah of course, i advise you to interpret on what makes your husband doubts about you and i suggest to communicate and solve the problem together.
