I started to realize that she had had an orgasm in the middle of the crowded dance floor

I shouldn't have left... but when my wife started dancing with her ex... and he started to pull her back into him... and he started to grind his hips tightly into her... and she pushed herself back into him... and then she started to shudder... and then she started to shouted, "I forgot how big you are..." and then she reached back to grab his... grab him there... THEN I started to realize that she had had an orgasm in the middle of the crowded dance floor... and that she was not coming home with me...
