what his type is isn't the problem. he's not hearing you because you've changed your mind too many times and given him a "second" chance. because of that, it's easy for him to tell himself that this is temporary.
by doing it the way you've done it in the past, you've not only heightened his interest via causing him to chase you (intentionally or not), but you've inadvertently given him positive reinforcement every time he's kept trying.
think of the situation as a slot machine. that's exactly how they deliberately get people addicted. by paying off eventually if the person is persistent.
if you really want him gone, you have to unplug the machine completely.
