Tonberry, I agree with you that his restriction seems silly. Especially if there are acts which he does not enjoy, and you want to do them, and he won't let you because he doesn't do them? That makes no sense.
It screams insecurity, and placing these restrictions on you seems like a bandaid solution. Bandaids are OK while the wound is still bleeding, but eventually it needs air to breathe and heal.
