Is he lowkey jealous?

So me and guy who I dated years back have gotten back to talking, so at one point he ended up bringing up the guy I had moved on with and hooked up with as a result of him seeing someone at the time. He said he wasn’t mad at me for it but for him to bring it up 6 months later sounds to me like it bothered him. He said he bets I still mess with him and I told him no. The guy he is referring to ghosted me after us hooking up so even if he did come back up I want no parts. He knows my heart belongs to him but what do you guys think?

Forgot to mention that when I said that to say he’s not mad about the other guy he brought it up he changed the subject.

So it’s more so his pride or because of his feelings for me?
