Do not agree anything until speaking with your lawyer. And do not talk to H. Let your L answers his L.
Remain no contact. For sure! You are in no condition to go this alone right now. Sorry, if that sounds harsh. I remember how f’d up I was when so anxious and hurt. Lawyers do this for a living and are not personally involved.
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
