Well, it's been a while, so let's start with what you think her top 5 needs are, and how you intentionally meet each one. Just list them out in the order that you think they are, from greatest need at #1 on down to #5. Try to include how long you feel you have successfully met that need.
Additionally, list at the bottom any habits you have which may be taking away love points from your wife (example: disrespectful judgements, guilt etc.).
Looking through your lists, maybe we can come up with some alternate ways to meet some of the needs, and perhaps determine what might be missing?
