Ignoring a guys text to see if he's interested?

I was thinking of ignoring this guys next reply and see if he texts me again in a few hours and test his interest level cause he's been unclear. Should I do this? I mean, if a guy cared wouldn't he retext me and see what's up?

If ignoring him is a no, what can I ask him to test his interest in the question game? LIke things that give him opportunities to hint his interest?
