For me one of the best parts of sobriety is self-confidence. I can hold my own with anyone now. No one gets to push me off my game or tell me I'm "less than."
The people in AA are flawed, we all are. Can you just chalk it up to, "Maybe that guy/gal is not destined to be my bestie"? AA is an unstructured social group with not very many rules and no leader so it's no surprise there are some people with serious boundary issues.
Or you can just hang out here with us and see how that goes. Have you read through the Secular Connections part of this site? Lots of great threads there, too.
