Does this sound like a joke to you?

Hello everyone i'm sorry if this violates any of the rules of this subreddit; I just have no one to talk to about this because I simply ✨have no friends✨.

I discovered that my boyfriend said this about one his close friends whilst him and I were together. When I asked him why did he say it, he claims it was joke and that I violated his privacy. I've been sitting down for a while and thinking maybe im overreacting and to just forgive him.

I've had this picture in my phone for months and i'm finally ready to talk about it. What do you guys think? Am I overreacting to an insensitive joke?
