It was just words, and he's a liar, so I put no weight into his saying "ok" or agreeing. I'm glad this is moving towards conclusion and hope he signs off when you return so this is as smooth as possible.
I unfortunately think CW is right. It was almost as if "I need her to babysit the puppy so I'll play nice for now." It could also be that he is just to a point of wanting it over so he is willing to agree to any reasonable terms in order to move on. But the "you are still going to watch puppy" comment has me leery.
