there could be a variety of different reasons you didn't hear from him, however don't drive yourself crazy trying to figure him out even though Im sure thats hard when you have met somebody you feel you are vibing with, which from what it sounds like just from ur post that you both vibed, which had nothing to do with sex being involved either....
men may act in the same type of manners outwardly but the reasons why they act like that for different men can all be completely different, the reason itself at this point isn't so important as there is a reason and for whatever reason that is he's not reaching out to you and bet its not personal to you even if it seems its affecting you
actions def do speak louder than words, even though words can feel great when the right ones are said....
If you had a good weekend and enjoyed yourself, didn't expend or compromise yourself or lose yourself take it as a good memory and hold onto the thoughts that whoever u choose to be in the presence of will see you as great and fun to be around...if he doesn't want to be that person let it go...he could of been full of crap or genuine and just has other things going on....regardless don't waste too much time trying to figure it out...
if the things he said made u feel good...know that whoever u spend time with or end up with will be somebody who finds you great and is ready, available or wants to be with you...def don't find an opportunity in this to beat urself down or wonder if something is wrong with you because of how he is acting
