I also have Chiron in the 11th house! Based on reading a few of the comments above, I’m surprised that it seems to not be normal to have a best friend for two years until the connection loses its touch.
I had really amazing friends in my life (I’m 16), but they always tend to drift off after a year or two. I actually find that very normal. I guess since I’m so accustomed to it, I don’t realize that friendships should seemingly last more than two years? I’m would be pretty confused about how Chiron in the 11th house would affect me if that were not the case.
Something I find extremely difficult however is establishing friendships in new places. A lot of the time, the people there already had a friend group they’ve known since childhood. So, I gets hard for me to fit inside the group. I blamed that mostly on my Mercury in 12th house Capricorn retrograde which I believe causes my shyness and inability to talk to people. I also have sun in Capricorn 12th so I’m very introverted.
I just read a few of how 11th house also would include dreams and wishes. I guess something that I notice is that when I hope for something to happen, it never EVER happens. It’s like, the opposite happens for me no matter what. When I don’t think about my wishes, it at a certain point comes true until I again, hope for it. I don’t exactly know if this would apply, but yaaa
