No, this is not normal. Unsure if this is a troll but if not, I'm so sorry that your partner is not being supportive throughout your pregnancy. It's completely normal to start searching for videos or information throughout your pregnancy as it's a weird yet wonderful experience. I'm unsure of how to go about this as it's a delicate situation, but I hope you have someone supportive in your life, like a sister, mum or best friend, that you could speak to about this to get their insight as they would have better knowledge of your relationship than us strangers on the internet, plus that way you can go into more depth with them about what's been happening with your partner.
But from a strangers perspective with the little information you have given, he seems like hes scared to become a father. Try have a conversation with someone that you trust and go from there.
