First, hurray for you for going outside your comfort zone!!!
Second, you sound very normal to me. Except for loving to read I doubt I wouldve had much in common with those women either.
Perhaps you should ask yourself if you were wishing you werent there versus them thinking that?
I've noticed the longer I socialize without alcohol the more I see that sometimes I don't have much interest in some people or gatherings, and when I drank, I assumed it was my fault.
Maybe it is no one's fault, it just is?
You seem to be a wonderful person. Perhaps you need to keep trying different things till you find your tribe? And keep alcohol out of the equation.
Anyway that's my plan. I know it is hard. Your post helped me feel less alone in this experience, btw. Thank you! And keep going! :-)
