I don't think he's leading you on, I think its his shy/reserved personality. Its a good sign if he's not trying to rush into anyting and its not like you're screwing around with him and he's bailing on you after telling you he likes you. I think give him a little more time. Maybe suggest group dates so he'll feel less pressure, maybe eventually he'll be comfortable.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
