Agree.
Do not downplay what has occurred.
Be factual.
Bring notes that state clearly a timeline.
Make it clear it was a mistake that you wished to move on from but that he has REFUSED to accept.
His career is NOT your responsibility.
Focus on your own career OP.
I mean this kindly but you need to wise up.
If you go into the HR meeting apologising and taking the blame for this mess, you really cannot blame them for accepting YOUR narrative.
Do you believe that this is all your fault, that you should lose your job, be gossiped about, have your card marked, have your professional reputation besmirched?
Because if you go into HR apologising for being born, THAT is exactly what will happen.
Make up some notes to bring with you about the timeline, you ending it, your wish to be professional at work and move on, his refusal, his harassment at work, at home, the tears, the trying to manipulate you to continue, you feeling you had to say you were going to leave as you were afraid, you going to HR for support, before you head to the police.
Make it clear you just wish to get back to work and move forward WITHOUT being harassed by a man 4 grades above you and nearly twice your age.
Tell them you feel intimidated by his seniority, as you clearly do.
