If you like him as well I'd say you have a great opportunity, I hope it works out for you :)
He's all yours if you want him!!! So he stops after a little bit - he just regained his poker face. The initial reaction is the true one.
he's either really shy (and likes you!) or something is on his mind. either way, the odds look good that he 4sure likes yaa
He is shy
he must be bashful, you've obviously stirred up an emotional response in him, he's trying to hide it...fail. sounds like he's interested, but you might have to pry him out of his shell to get him started.
obviously that means u got a chance for him to be ur mann lol
