Most Helpful Guy
All guys love the chase, but all guys also love getting praised for achievement. If a guy chases a girl and does not feel like he is getting any closer to his goal, he will give up the chase. If a guy chases and gets his goal on day one, that it was not worth it and he will something is wrong.
There must be a way you react that makes this particular guy feel like he has achieved something. Do back off, but do find out what makes him tick. Best way is to find out his interests and show interest in them. Not too much interest since you're not an item yet.
