English help: Geoffrey Chaucer paper

Hello, I'm right now at a point where school is going to be over and I must do an English final paper in my Chaucer class. We have read his Canterbary Tales (interesting read) and Troilus and Cressida (had trouble understanding). I want to do my final paper on love and marriage. I got out of Canterbary Tales a good deal of things and some biblical ideologies, but Troilus and Cressida I haven't read all of it yet. I'm on Book II and understanding it in modern language while reading it in the original language. I'm in Book IV in our class. Anyways, I need some sources or some information about love and marriage in that story that might be really good. I have been going to the library to do some reading. Anything would help, please. Thankyou.
