I feel the same as scorpiosis and I said it earlier, if the very first conversation ends with "bye" it is a sign there will be nothing further. Of course he might be just shy but then he'd call back. Also notice you are the one again who called twice, sometimes it's ok to wait for other person. I think people suggest reading books on dating as to get familiar with basics of dating.

Also do other things. Join meetup groups etc get out there. Get a second job etc
