I never thought of it as a serious romantic relationship, at least from Garak's point of view. Garak was very fond of her, but he didn't act attracted to her, and Ziyal seemed to like Garak in a cutesy kind of way. It seemed very much like a platonic romance, if such a thing is possible. To me, their relationship is more fuel for the Garak-is-gay argument, because here's this smoking hot chick who's really in to Garak, and he's just totally baffled by the situation. I really think that Garak was in love with Julian, who appeared to be clueless throughout the whole series.
I don't think the age difference is creepy. True, Garak could be 20, 30, or 40 years older than Ziyal, but we're not talking about human courtship standards here - besides, they're the only Cardassians on the station, and they're both adults.
