As someone who went through pretty much the same thing (she broke up with me and was confused why I was sad about it and wanted us to stay friends at first), he is not your friend. Assuming this breakup was not consensual, this is not something a friend does to someone, and you should not take any heed to his "feelings as a friend". It sounds harsh, but with breaking up with you he not only ended the relationship but also the friendship.
In my own experience, I was only able to move on from my last long term relationship after I accepted that we were not friends, she did not value and respect me and any progress I could make as a person are when cutting her out of my life completely. It took me a few months to get there, and I am better than ever a few more months after that. Before that point, I was constantly in pain and barely functioning, but after the decision to view my ex-partner as culpable for what transpired, I was able to heal and move on.
The Gentlemen Bastards series could work well: Not too much CGI needed, and fancy rennaisance italy aesthetics deserve a fantasy show about thieving orphans!
