What does it mean when the guy I’ve been seeing invites me to watch his softball game?

I’ve been seeing this guy for the past 3 months. We never labeled what we are. Anyways, he invited me to watch him play softball. After the game him and his friends were hanging around the concession stand. When we were about to leave one of his friends shouts “by (my guys name) girlfriend. Can’t wait until the wedding”. My guy didn’t correct him but he also said he didn’t hear him. When I told him what he said he didn’t make it a big deal or say anything about what he said. I’ve also met/ hung out with some of his friends. He also recently introduced me to his brother. Are all these good signs?
