If I were in your shoes, I would leave it be for a while. He needs some time to mull over the email conversations for a bit. He knows now that you are okay and aren't angry w/him...so give him space. You've opened the door for communication and now it's up to him to step over the threshold.
Now, it's time for you to focus on yourself and do what you need to do to move forward. You can't make him or his journey move faster for you...so you have to take care of you until he either gets thru his crisis on you completely move on.
Lou, be kind and gentle to yourself. You've had a lot of stuff going on and now, you need to tackle each and every obstacle, one by one, i.e., it's like rebuilding your life, one brick at a time. You've got this. Don't try to build your new life all at once...it's a step at a time.
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.
