Might want to look into finding a pdoc/neurologist who is familiar with apergers. Some of what you are saying here is very similar to what I was dealing with my H for so many of our married years.....he's not Dx'ed either but the more I research the symptoms, the more I'm sure that was the problem with him in our marriage......& getting certain things in your mind......thinking opinions as fact can be part of that.

The mind is very complex & when we do not gain the skills we need growing up....we have to learn them as adults & it's a lot harder doing it then because we have to UNPROGRAM the old & REPROGRAM the new....& there are some disabilities that make that even more difficult.

Keep pushing to find a pdoc willing to do a thorough evaluation. My H went into an ADHD study as an adult & pdoc stopped at that....but also told H that he needed to go to a neurologist because he thought there was more wrong with him than JUST ADD.......& now after researching the asperger's, it's the only Dx where all the symptoms fit what I experienced with him.

He grew up in a family that moved all the time with his dad's engineering career, so not having friends seemed like a normal situation to come out of that....so some things do get masked by our growing up circumstances. Just insist on having a thorough evaluation that covers all the different possibilities & that they will be open through T to keep investigating so that you can know what is really going on in your mind.
