Please, please, PLEASE don't wave the post-relationship white flag like that. You say you put him through hell, but is that the reality or just something you think is true? (either due to your own potentially low self-esteem or something he made you think) Or maybe you were just joking?
One reason you shouldn't is because it makes him think that it any s**t of HIS you had to tolerate is ok. It tells him that he's off the hook for any blame. Unless one party did something extremely hurtful (eg. cheating) relationship breakups are always a two way street. I hope it wasn't a case of just saying it to make him happy. After all he is the person who edits your videos. Maybe you feel pressured to only talk about your past relationship in a self-blamey way, otherwise he'll get upset and refuse to edit the video?
