Partner not wanting to be in the delivery room

I was wondering if any one could help me with the current situation I am in. My partner has announced he would rather wait outside until the baby is born then come into the room. I thought he was generally joking at first but he isn’t. This is my first baby and I’m really scared as it is.

My partner really does not like blood and he is also autistic which I think doesn’t make the situation any easier. I wish I could understand how his mind is thinking. I’m trying not to be upset or angry with him but I really want him in the room as otherwise I will have to go through it all alone.

Has anyone been through anything similar or has any tips on how to make my partner feel better if he does come in the room?

Thank you💙
