My boyfriend showed me a video of him having sex with someone else telling me do u think I will cry if u disappear?

He thought I was cheating on him with my manager I told him I didn’t he never heard me so I stopped texting and calling , he was happy showing me the video and he was the one who managed the new date after 3 months of breakup, why did he hurt me and is he a narcissist?
