I'm glad you went to dinner and were able to observe his behavior in a relaxed setting. Sounds like he's settled down a bit and is coming across as a friend right now. Listen closely and sift thru what comes out of his mouth. You'll learn more this way rather than asking questions.
As for his time frame for leaving, time has no meaning to them. He may think he's got an additional week or so and didn't realize his departure date is right around the corner. Again, time is very slow for them and they don't remember dates very well.
As for him spending time w/you to discuss business issues, can't that be done at the office and not in your home? What about going somewhere and discuss issues over coffee?
I would take advantage of his good nature and if he wants to help you hang flower pots or whatever, take him up on it...but be sure to thank him for it. In a way he wants to be needed and recognized for his work and after all, he looks to you as a good friend right now. Friends help friends...right?? But, again, you have to decide whether or not you want him around you in your space.
Time is a very precious gift and we all need to use it wisely, but also enjoy ourselves in the process of learning about ourselves.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
