A lot of romance/companion story triggers in the game are still buggy, and Gale's is really the hardest one to have work. I actually made detailed suggestions to the devs on how they can address the elusiveness of companion camp scenes via the forums (https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=762606#Post762606). It would be best if we make more noise about this across all the BG3 forums so Larian may prioritize addressing this problem during the development of the game.

That being said, you can follow the detailed guide commented on this reddit post to trigger the Wizard's romance while in EA - https://www.reddit.com/r/BaldursGat...les_buggy_romance_arc/gphgr75/?context=3
