What do I say to that?

So I was out with friends and I was chatting up a good acquaintance. He’s a nice guy. Last time I saw him he told me very enthusiastically that he now had a girlfriend. I returned the excitement and said I’m so happy for you! But last time I saw him I asked him about other things and then asked how his girlfriend was. He just responded to me with a smile and said “still emotionally unavailable”. So naturally I said oh that must be awesome for her. And he said no she hates it. lol why tell me that? What do I do with that lol. Very odd Interaction. I was sure what to say so I kinda laughed and stopped talking.
