Advice for giving birth alone, without a birth partner?

I’m thinking of doing it alone, this is my 3rd baby and partner hasn’t been supportive. I always make my own decisions as he is always away for his business. So I’m like what is the point of him even been there 🤷🏻‍♀️ I’m also due a week before Christmas so childcare around that time is limited due to our children been off school.
