A new stove? That's wonderful. It sounds like your h is sitting on the fence and can't decide which pond to dip his toe. Some of them use "us" when they are speaking and it's because they forget why they are upset w/us and or it's an old habit that they are use to. Some will want to purchase things for the home or go out and buy things for vehicles, etc., because they forget why and where they are living. Sometimes they purchase things for us because they feel guilty about what they are doing. I think it might have been a slip of the tongue when he had moments of clarity.
For now, it's good to have hope and I do hope that he sees himself coming back eventually. It's difficult to say what is really going on in his mind these days.
But, I'm very happy that you are getting a new stove and had a great week.
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.
