To the OP,
I've heard it said that before marriage, you should have your eyes wide open, and after marriage (or perhaps I should say, within marriage), you should have your eyes half shut.
I've also heard it said that if there is anything which irritates you before marriage, deal with it or walk away. The things which you find 'endearing' in a relationship will irritate you within a marriage. The sound of laughter is a great example, because it should be something which brings joy to a partner.
