I think it is understandable to seek answers to these sorts of questions, but the reality is that they are questions no one can answer for you. Each of our stories is different; the people involved different; the circumstances different.
It sounds like you guys have been able to keep a good relationship throughout this and that it was not unpleasant for you. If you are inclined to keep seeing and/or talking to him you may learn something over time or you may not. It might be the start of something, it might have been an end of something for him. Time will give you the answers you seek.
Of course the original DB advice probably applies now more than ever. Keep moving forward with your own life. Don't have any expectations of what is happening or why. Participate if it provides something for you, decline if it doesn't. Make your best life for you.
