Sounds to me like you move fast. Maybe you're just super efficient?Maybe my 5e campaigns are also blitzes? I've run campaigns like Rime of the Frostmaiden and Curse of Strahd to completion. They took around 6 months of weekly play - close to 20 sessions.
At any rate, if I were you, I'd try to slow down a little (only because a player complained) but otherwise just keep going like others have suggested, and have a post-campaign discussion to see if it still felt too fast to that player (and find out if the others agree) and to what extent.
