You are very new to this crisis stuff, but you've got to stop analyzing everything he says or does. No, I don't think that the fact he walked you to your car, kissed and hugged you were a bit more than just friendly. It may have just been a moment of clarity and a habit from the past. I wouldn't read too much into what he did.
They do all sorts of things that can make you think and over analyze stuff. Some will do what your h did when leaving you in the parking lot, others will bring you gifts or do good deeds, but in their minds, it is nothing more than being a friend doing something for a friend.
Keep your expectations very, very low and continue focusing on you and moving forward.
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.
