Love Language by Gary Chapman is a book that should be a must read at some point during the LBS journey. I also got my wife to read it and it did help figuring out what her LL is. There is a little test at the end.
The 5 LL are
PT = Physical Touch WOA = Words of Affirmation AOS = Acts of Service QT = Quality Time G = Gifts
The idea is that each of us speak a primary LL. Once you know yours and you can maybe guess your W, you will have a non verbal way to communicate. As we say believe none of what they say and 50% of what they do. You each may be speaking your LL and expressing your love for each other even though your words say something totally different. Sounds like your LL is AOS. But you want some WOA from her. I would recommend the book if you haven't read it. Check out the library. The book can be read in 1 or 2 evenings.
