Naruto knows that this point, he's the one who has to make an effort to restore the relationships within his pack. HE can say there and feel bad about Anko, and complain about Kiyomi's actions but nothing will be resolved if he doesn't take a step himself. Pouting and being angry will not solve the underlying problem. As for Kuukaku, she found pleasure elsewher. I essentially see Naruto's mindset as the following, the bijuu are free for the first time in millennia. IF they find happiness or purpose elsewhere but not with NAruto, I would imagine he'd be happy for them. If they choose him anyway later, that's also good. How the remaining bijuu come to love Naruto is what will be interesting to read about. I'm more worried about the meeting between Mito and Kushina considering Naruto will probably see the similarities in Kiyomi. The face of his clan kin and the body of his mother. Like I said, fun reading ahead.
