To me it doesn't sound like this will go anywhere and while he has been nice in the past, he wasn't that gracious to you. I don't hear that you were waiting for him to leave the gym and so what, big deal that you walked over to the table to chat while you waited. So, if I were you, I would move on from him and not take any of this personally.
There are not rules on how this goes..it comes down to how you feel about yourself and what energy you want to put out there for a man that has shown his style. It is usual that people show themselves early on and so he has. Let that be your guide.
Let me know if I can support you further. Keep your head held high and try not to personalize any of this.
