Accept him for who he is today and try not to "over" analyze anything he does. He's different now, so maybe he just went ahead and took care of your horse for you. I don't think there is any hidden agenda here w/what is going on in his mind right now.
No, I don't think divorce is on his mind right now and I wouldn't even think about this as a stepping stone of niceness to pave the way to one.
Let it go. Be sure to thank him for doing the things around your home for you. Again...accept him for who he is today.
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.
