I have the same problem. I also find it simply am not interested enough in making new friends as I'd rather stick to my comfort zone. I also say odd or inappropriate things that I think are good but others don't. I also can offend or upset people when I believe I am simply being rational.
In as much as we on the spectrum can be so different, I'm apt to speculate that what you posted may be very common for many of us. I know it applies to myself for sure. While on occasional I get out and make superficial social contacts, I don't seem to get much of out if these days and tend to be more content in near isolation. Even when on occasion it gets lonely.
Contradictory at times, but "it is what it is".
