He's practically telling you that he's watching and okay coming around to this different you. Make it comfortable to be around you and your D.
As long as you keep the mantra "NO EXPECTATIONS" you will be okay. Don't expect nice guy to come around for good. He's testing you. So drop that rope and just continue doing your Musey things.
I think I read this 10x last night. No matter how much Counselling I've done, nothing tells me the how to, of working things out. I love my counselor, he's awesome and he helps me work on issues, but the step by step of solution oriented results has evaded me.
And as funny as this may be, I have dealt with horses (from evil ponies to big warmbloods) most of my life. I applied everything I knew about horses to being a parent, my D is a great kid. And now I am using it, and the practicality of what i am learning here, to how I think about my M and how to try and get it going in the direction I would like it to go.
It may sound strange but calm, patience, never chase, reward any small step in the direction you want to go, are the foundations of building trust and a bond, with a partner (horse or otherwise I guess).
Let's see if he calls today, and let's see if he remembers the movie on Sunday.
