Hi, Bee, and welcome! Have you read Fibro 101...the first thread on the forum? There are some great links that could help your situation. When you first open Fibro 101 there is an interview with one of the top doctors for fibro, Dr. Daniel Clauw, and what they think is causing this illness. It is very clear and easy to understand.
There is a link called A Thorough Explanation of Fibromyalgia that helps explain this illness too.
AND there is a wonderful link called Doctors Respond to New York Times Article. The NYT had an article that said that fibro wasn't really an illness. Well, learned doctors who have dealt with and studied this illness came out of the woodwork and corrected them.
All of these are very good but I see that you said he wouldn't read the literature. These things in Fibro 101 are relatively short...it's not like you are handing him a book to read. If he refuses to read these things, I think, if I were you, I would end the relationship. He basically is calling you a liar and won't take a half an hour out of his life to read something that is so important to you. I guarantee that things will not improve if he is not willing to make an effort to try to understant the pain you are dealing with.
I know that's not what you want to hear but I really think this is true. This is, of course, my personal opinion. Look how unhappy you are right now. You don't know what to say to him. There is a large rift in your relationship because he won't even make an effort. Since doctors are not positive what is causing this illness, there are no cures so you will most likely have this a very long time. I don't think you want to spend your life defending yourself from being accused of lying. Fibro hurts. We need people to help support us or at least make an effort to try to understand. No one can understand this illness fully unless they have it themselves.
I hope he will read these articles. You can print them out for him to read or read them to him. Do let us know if he will start listening. Have him come on the forum and ask questions or just let him lurk and read some of our posts....including Fibro 101. It could make a big difference in his attitude if he will do this.
I'm looking forward to getting to know you better. Don't hesitate to ask questions because we are here to help you. Hope to hear more from you soon.
