I read this really fantastic book (maybe some others on here have read it too) called the five love languages. It talks about how there are five love languages (obviously) and that most of the time a husband and a wife have a different "language" but that we usually try to show love in our language. For example one of the languages is giving gifts and this might be what you are doing with the flowers etc. because you think that is something you would like, but maybe her love language is quality time (or one of the other languages) and she would rather spend time with you playing a game or something than receiving gifts. I hope this makes sense, but there are five different languages and I thought the book really made a lot of sense. I am not suggesting this is the only problem but find each other's love language and learning to "speak" it might help your relationship some?
