How can I ask him if he's interested and where I stand without seeming desperate or

aggressive? This introverted shy guy I've been talking to seemed very interested but I had to make all of the moves (initiating contact, asking him out but he had to cancel, etc) because he's so passive (inexperienced and so I guess scared at first?). He hasn't replied to my last 2 texts and I'm very confused if he's suddenly changed his mind about me or what. He would always respond enthusiastically before and talk to me and jumped at the chance when I asked him out, he always responded to my advances and not just in a polite or passive way but enthusiastically/encouragingly but he wouldn't do much initiating himself. What can I say in a txt to just ask him what's going on?
I just want to know if it's that he's busy or shy or whatever or if he's not interested in talking to me anymore so that I know what to do and don't make a wrong assumption - I don't want to waste my time or his, or hassle him. If he says he's not interested, that's fine, no hard feelings, so I don't want the txt to sound angry or like it's a big deal. I just need some reassurance if he wants to pursue anything!

'Hey. This is my last ditch effort at getting to know you because nothing is really happening and I really can't read your confusing behaviour at all; I can't tell if you're just polite and don't know how to say 'no thanks' and don't want to talk to me at all, or if it's something else like you're just reallly busy or passive or whatever. No hard feelings or pressure or anything either way, I just like to know where I stand because otherwise I don't know what to do and I don't want to waste my time or yours so an honest answer would be appreciated to clear things up =]'
