If this selection problem has been going on for several months ? then I doubt it will change anytime soon. I am surprised your Sensei has not noticed – or maybe he has, and chooses to ignore the problem. Your problem is a much wider one than you may imagine. I have seen these `aiki-friends` attend large seminars where they should enjoy meeting and practising with many new people, they don’t, they still practice with `their aiki-friends`.
I hope you do not give up on Aikido, but you need to move from this dojo.
