Treasur, I'm impressed you got a response. Mine would have completely ignored that and said nothing.
What is the real hope? That he will resolve the money issues or that he will declare it a mistake and come back. I thought the wording of your email quite interesting. Just don't set yourself up for a fall and your expectations very low. My guess is that if you do hear from him, it will be a vague mess of a conversation that doesn't really resolve anything.
