I don't know if he is a narcissist & I don't believe it is possible in diagnosing other people online.

What you write about however, shows a major red flag. I would address it asap so he does not continue the habit of insulting, controlling or gaslighting you. This is not how a loving partner treats their spouse. He, and you both, ought to work on how you communicate with one another *before* the baby is born.
