Amelie, I think fellas DO usually call if they're interested in you, not just to make another date, but just because they want to maintain contact and build the relationship. If this is frustrating you at this point, I say blow it off. Maybe he'll call; maybe he won't, but it's not worth the anxiety you're experiencing. You are lovely and needn't be putting yourself down or feeling inadequate. Yes, dating is hard (for me also to the point that I've stopped entirely...but I'm much older).
It would be helpful in giving you feedback to know what was the nature of the date? A first meeting...How did you meet him? Is this the fella you wrote about previously? or someone new? If this is, by chance, someone you met on an Internet dating site (nothing wrong with that, BTW), just know they are possibly meeting a lot of potential dates...that's just the way it is with Internet meetings/dating.
