Of course as the flying pilot, you should be tuned up to the current situation and possibility of ATC giving you the option to turn in but that's not really the issue here, many accidents were caused by actions you describe when the captain tries to save the day, I would request a debrief with him and if he doesn't admit that he was in the wrong, I would consider reporting this to management. Make sure you get what you need on the tape too, sink rate, unstabilized, go around!
