Let's say that the question is about whether he knows where he stands at so that I can know where I stand at. Might he just have forgotten to reply? Why wouldn't he then just ignore my message instead of asking me to wait because he was busy but that he will reply? Is it a way to tell make me pissed off and just leave it? Has he no courage to tell me the truth? Does he want to keep me hooked the time he figures his stuff out?
