I don't want to sound condescending, but I am proud of you Emily. I truly hope your H gets the help he needs. Your offering to be his friend is noble and I hope he appreciates that. Just be sure to protect yourself and not get sucked into anything.
Keep working on you Emily. Keep plotting your own course. Keep learning from your past - not only your mistakes, but also from the good things you have done in life. This incident obviously caused distraction for you, do what you need to do with it - and then keep moving forward!
((((((((Emily))))))))
You have come very far in this journey. Keep it going.
