Oh, I'm sure he believed that. And I'm sure that we're meant to, as well. That's the real problem with the prequels, though - this revolving door of characters who are on for 3 minutes and we have no way to know, much less care, about them. And there's absolutely no shading to anyone, whomsoever. But buying a slave, just to marry her ... that's just too suspicious to simply "accept." There's something going on, there. Some psychological impedimentia is at work ... not too unlike a teenaged Padme taking to the awkward flirtations of a 9 year old slaveboy. This whole family's screwed up. They say alcoholics are drawn and attracted to eachother, without even realizing it. I suspect this is a variant on that theme.
