A comment was sent to your DM

I was dealing with my phone when the notification sound suddenly popped up in front of me. I saw that he commented on his ex-girlfriend’s photo in front of everyone. Worse still, he sent me a DM with a message like, ‘but look, I wrote it just for fun.’ Now I can’t decide whether to argue or just act like it never happened. Honestly, the topic of his ex has bothered me before, but I always brushed it off.
