Emily I hope you won't be offended, because I understand that need for true friendship, but you do have some very specific expectations. I wonder if you are discounting people who may very well have turned out good friends.

For instance you could meet someone who did not work all week like you but was fine just to meet up when you were available. Or someone who had kids (maybe grown) who did not talk about their kids all the time or her husband either. Sometimes people enjoy having a break from their families.

I think similar political beliefs is a little more understandable, that makes for more accord. But otherwise I think different sorts of people can become good friends.

I do hope you can meet people who are good potential matches, but like I say it's possible those best matches may not be quite what you are describing.
