I agree with Lisa, don't worry too much about what he said. I don't think there is a whole lot of planning ahead going on in his head. He's got grass growing, and he needs a mower. He isn't thinking about whether he'll need it for a week, or a month, a summer, or forever.
As far was what he is going to tell you, don't expect much! He is probably still feeling himself out, and to some degree you as well. Not that you haven't been clear, but in his mind, who knows? Everything you have said and done has been filtered by his confusion filter, so what's clear to the normal person may be totally out of focus to him.
I really think you may find your patience really being tested in the next few months!
