Woo-er. Hm, there's a book on King Arthur by Kevin Crossley-Holland, and it mentions Courtly Love in there. It's called "The King Who Was And Will Be", and I found it interesting, but you might find it a bit limited as it's mostly about Arthur. But that's all I can think of, sorry.

Personally I wouldn't go for Crossely-Holland. Courtly love didn't stick in my head from those books.
I'm sure there must be loads--try to find stuff about Eleanor of Aquitaine, who basically propelled courtly love into society with her romantic court. Look up stuff on troubadours as well. It's a bit of an obscure topic, but I know there's stuff out there. Good luck!
That last link has the codes/rules of courtly love, which should really help you out through your writing. Those rules will dictate a lot of the action.
I'd suggest some fiction to you, but it's all rough reading and I don't remember titles.

I had to do a whole load of research on this for my English Lit exam in Chaucer - there's a whole code with definate rules on what to do and what not to do.
