"He won't even entertain my options and is adamant that he gets his way. "
You do realize that this is just the first of many things related to baby's care and upbringing you are going to disagree on for the rest of your actual lives?
And if you cannot agree on this, and if he is such an obstinate arse about this, then I think I would reconsider having a child with this man.
I hear what you are saying about him not generally being a dick, but as an unmarried couple without kids, you really have not had that much of importance to agree or disagree on thus far in your relationship! If he "lets" you do household decisions, this only means that you are responsible for domestic things, so he cant be arsed to decide.
Why on earth do you want a child with a man that is not keen to listen to, and discuss your views? That is a very unattractive treat in a man. Not respecting you much here, is he?
You are creating a massive rod for your own back here.
He is also wrong about tradition. He is asserting his stance based on incorrect assumptions rather than knowledge. Tradition is for a woman to take her husbands name on marriage, and for a child to keep mums surname if mum is unmarried. He has created a "truth", presented it to you, as a reason why his wishes should count, and not yours.
How long have you been with him? Surely you can do better than this?
