Jason and Reyna never dated and most likely never told their feelings to each other if they had any in the first place. Reyna feels something for him, but Jason only said at the end of The Lost Hero that he definitely remembered a girl named Reyna, most likely because she was the other praetor alongside him. Once Jason got his memory back, there would be nothing preventing him from dating someone else as he was never romantically involved to start with.

Also, during the book she seemed more concerned about her father and the fact that she is leading her friends into a death trap than dating Jason.
