I asked awhile ago for your definition of NEE (and EE for that matter) but see nothing.
In your example of the girlfriend I see some empirical evidence: for one thing I (and any others ) can confirm the existence of the g/f. We are also able to measure physiological changes associated with love. Some form of these measurements can be made with animals and compared with the human reaction (removing some of the subjectivity).
This is not non-empirical in my view but I don't have your definition.
