I agree w/pinn. He needs to be the one to initiate the invitation. Allow him to pursue you for a bit. If he doesn't contact you, just let it go. Trust me, he'll contact you when he's ready.
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.
