Don't panic, VS... it sounds like you did very well...
But my personal opinion is... don't hit the accelerator... what you are doing appears to be working, so continue to allow him to chase you... don't run too fast... but don't start chasing him...
He's told you what he likes... so keep going with the banter... you might want to toss a valid compliment about him every once in a while... if there's anything you can think of... something new he's doing or some successes he's having in his life...
And a little flirtation now and then...
Just opinions... but keep your hope and expectations in check...
