i am happy you stayed in touch with this guy, he is probably just very busy and din't get around to your post. i wouldn't give up, but don't make a groupie of his!!just joking. he may be interested in you , you won't know until you try, i see no problem with a woman asking a man if he's interested in you, just so you know and don't waste time on him if he's not, but it seems like he maybe is.
