Like Coly him not wanting to be done stood out for me. It'sgreat you didn't pursue that with him. Are you in a place where you could be receptive to another R with H? Just curious. Whether you are or not, let him expand on that on his own without you bringing it up.
I am not sure I could trust someone who has already left his family, though you are right that it could be interesting to have his perspective of things.
Best wishes
