I would just simply read the references on it in the DR book. It is working for you. It is really a very simple concept. You give what your partner needs and wants not what you want them to need.
ex- Your spouse wants space, you give them space by not talking about the R, letting them do their own thing. You don't try to find out what is wrong or work on the R.
I find if you listen very well they will tell you what they want, just don't be affraid to give it to them even if it may cause you some hurt (kind of like setting someone free so they can choose to come back if they want to, you don't want to, but you need to)
Read through some of the threads, the board is covered peoples spouses telling there partners what they need from them.....listen. It is not something you necessarily formally implement like the 5 LL. It is something that should come natural when you follow your heart.
