Good questions. I would say to let him know in a very non-threatening, non relationship pursuing way (matter of fact) that you have a history together and he will always be important to you. That he can always talk to you and trust you as a friend if he needs one.
But you have to be ready to be a friend that can handle almost anything that comes your way. It doesnt mean you accept what he is doing. You said a lot of good stuff in two posts back. If you feel this is what God is putting on your heart, you should reconnect with him in a way he can handle it. If you arent ready, dont push it.
