He might have said the same thing about you!
IMHO, I don't think saying goodbye is pursuing. You might be coming across as distant--you want to seem receptive, but not like you're holding your breath.
Ask him how his day is. What movies he wants to see. If he's read any good books lately. How his bike ride went. That's just being interested, not pushy.
And if trying to get him to pursue you doesn't work...well..time to try something else.
