Annabeth Chase and Percy Jackson are fictional characters from Rick Riordan's "Percy Jackson & the Olympians" series and its sequel series, "The Heroes of Olympus." Up until that point, they did not break up in the main book series. They were portrayed as a couple who shared a deep bond and faced various challenges together as demigods.
However, please note that my information might be outdated, and there could have been developments in the series beyond that point. Rick Riordan may have released additional books or short stories featuring these characters, which could contain new storylines or events.
If you are interested in finding out the most recent developments in the series, I recommend checking the latest books in the "Percy Jackson & the Olympians" and "The Heroes of Olympus" series or visiting the author's official website or social media pages for updates.
