If your marriage has reached a point where your wife is so suspicious of you to check your phone without you knowing, or check your emails behind your back, then it's time hire a divorce lawyer.

I understand the argument that if you don't have any secrets, then there is nothing to hide.

But if you don't have reason to doubt, then you wouldn't look in the first place.

If your husband/wife distrusts you that much, your marriage is over.
