Phone call etiquette

I think everything went well and you gave him your #, but him not calling I understand he was busy but he should have at least called to say hi to sound like less of an a$$hole since he never even tried to call.But I think if I was in that situation I would have not giving him my # and said if its meant to be then I'll see you again but in certain circumstances I would.Because you might just run into him elsewhere and get a feel of him.Because its hard to tell in those few minutes when you get #, what a guy is really all about.So all in all I don't think he is really serious about calling you so just don't even worry about him...you can find some other guy
