I liked Geordi and Leah on the holodeck, but I stopped seeing them as a possible romantic couple after they met in real-life. Novels (and one now defunct alternate timeline) aside, Leah is already a married woman with a busy career of her own. She placed Geordi clearly in the friend zone, IMO.
I've kind of held a view that the Enterprise-E never strayed too far from Earth, or was never deployed on a long multiyear exploration mission, and that Geordi started his family during that time. I'd like to think that the mother of his children was someone he didn't see coming (no pun intended).
