You should consider reading The 5 Love Languages. I'm going through it at the moment and I find it enlightening to understand how to connect with a spouse. It's possible that all those years you've been speaking a language that she doesn't understand. Perhaps you're a gift giver and she wants quality time. Perhaps you're a physical touch person and she wants to hear you say words of affirmation. Have a look at the summary at least and see if it could be of interest.
