There are some very unkind comments on this thread and a woeful lack of understanding of the autistic condition. It often isnt the case to just get out there and broaded the number of people you trust/enjoy being with. I know that my son, who is intelligent and articulate with a quirky sense of humour has tried (oh Lord, has he tried!) to "mix". But try as he might, he doesn't "get it" and, people dont "get" him. He has, for the time being, all but given up, as it is so immensely stressful.
If a person found it difficult to walk a tightrope every day and just kept falling off, and got no pleasure whatsoever from doing it then it might be reasonable to give up that activity or at least do it less and less frequently. That's often how it is for me (I'm a late diagnosed Aspie). I had a career in the NHS as a nurse (Staff nurse and 15 yrs a junior then senior Sister). I "function" well. I am engaging and sociable to a point. I've few friends and many acquaintances; it is exhausting to be around people socially too much.
OP, there's nothing odd sbout your situation. For many people, it is "odd" those socially adept folks who genuinely need a miriad of relationships. Some people don't. I have two friends I can call close and beyond that, I have my mum and sister. We are "close" and I feel utterly "safe" with them. I have tried to broaden my world, joined things which proved to be too exhausting to keep up, in the long run.
You are not odd OP. It's not weird. There are loads of us out there 😊
