No, no that is probably not it you must expres all of your feelings to him, I know what Apergers are but do not give up ^^, you should go to him, how far is he? and apergers......... i knew someone with that but that means that you have to overcome it, and just feel that what he says and transcribe words with the emotion behind them, and continue writting to him, and send things asking if he likes you at all, how long have you known him? and go to him, eventually if you want to and love him enough then you will both end up together, I know that might sound overplayed but it is true ^^
and I will be back later I have to go somewhere thanks again ^^
and, dont give up on him..., i am sure he reads your messages ^^
