And no, you’re not crazy for loving Belle. I love her too. 😀
And I agree that Belle isn’t directly connected to the curse, but I do like your theory that Rumpel became obsessed with bottling true love after Belle’s supposed “death.” It makes sense. If Mr. Gold was willing to murder a man over a chipped cup, it wouldn’t be too far of a stretch to assume that he’s also created spells inspried by her.
