The best advice I can give you is that no matter what visa you intend to pursue, time together in person is most important. As much as you can. I understand the issues with your disorder and I pray you can find some treatment that works because with him being from a high-fraud country, time together in person is the thing that will convince the Consular Officer that your relationship is legit. I know that this is going to sound cold, but they will not give a care in the world about your disorder. If you do not have significant time in person together, even a spousal visa will be a severe battle for you. If you do the Utah Online Marriage route and go to "consummate" the marriage, file the I-130 and don't return for more visits while it is pending, your likelihood of getting the visa approved there is somewhere between slim & none. I'm sorry if this all sounds doom & gloom but I want you to be aware of the realities of your situation so that you know what you must do if this is how you want to proceed. The consular officers in these high-fraud countries have never been known to be lenient, even in the most permissive of immigration environments and in the current climate, I imagine that they have an even wider latitude to deny cases on suspicion of fraud. You are going to have to prove to them that your relationship is legit and unfortunately there is really only one way do do this - by getting on a plane, a few different times, and spending time together.
