Eh, my usual response... I wouldn't have posted all this information, including the AIM conversation, until you clarified that you were UPSET and then got a response about it.
It sounds like yeah, he was stringing you along for one reason or another. Whether it was in good faith or bad faith, I don't know. But either way, you didn't really show any "opposition" before posting this. I would have made your opposition, frustration and problems VERY CLEAR to jon himself - giving him a chance to respond to an obvious "crisis" before making the crisis public.
But... that's just me.
