I don't think so. I think he is ambivalent and perplexed to the same extent as you are.
you say it yourself, you don't feel like re-marrying him or anything, but just would like to see if there is something there. he says the same thing, almost word to word. He says he would like to see you - often - but is now afraid to re-commit. he is even admitting that perhaps there will be more in the future, but who knows.
Now, sit tight and think back in time. YOu obviously still have feeling for this man, and still can recall happy times. I would bet you fall asleep thinking of them! but for a moment, try to remember the bad times that led you to a divorce. Why did you get there? what did you feel? If you have a girlfriend who helped you throught the divorce, contact her and ask her what you used to say. try to get a reality check...
Perhaps there is still a life in your relationship. but perhaps it is only a nostalgic spin. try to make the difference.
Love
