No all guys do not love a chase. I always hated it. I think only the extrovert guys see it as a game which they don't care too much if they win or lose a round. The introverted types see 'wearing ones heart on ones sleeve' as more serious, a vulnerability that gives the girl the opportunity to make a fool of you, or to make a fool of yourself. So a favourable result is more important to them when they do take the risk.
This guy has expressed interest first already. Texting, saying he's free Saturday night. it's perfectly possible that if he's not texting so regularly now, it might be down to the impression given by a lack of response. Admissions like, "I wont text him 1st though", suggest that might be the case, although how one can text first when one's already received a text, boggles the mind.
How about giving the poor sap some encouragement, if you are serious, or telling him he's wasting his time if you are not? Stop playing games with him.
