Is it corny for an ex to talk about a new girl/guy in front of you? why do they do this?

We were in a space on social media and the topic was about sex. Someone in the room ask a question and my ex answered yes a woman he’s been talking to for a couple of month was at his place and she pulled him by his dick. I get we’re not dating anymore but I wouldn’t say something like that knowing he’s in the room. He was in the room first but I came into the room with my friend not knowing he was in there. It’s a room on social media. I just feel like he wanted me to feel away or may e not but he was mad about our break up. I broke off the relationship.

I guess I’m trying to see if he was trying to make me jealous or make me feel like I wasn’t anything to him bc he already sexually active with someone else. It’s been a year and we been talking about having sex that entire year but we broke up. Long distance relationship. What you think.
