Idk it’s his 11th so maybe that’s why there’s no joy. But it doesn’t seem like he doesn’t want the baby given everything he’s been doing especially with the vitamin. I’d say have a conversation with him about how u feel
Is he just not a party/celebration person? The fact that he is being so supportive of you and the pregnancy makes me think that he does want the baby. My partner would never throw a party or invite his folks for a celebration but he is certainly excited to be having a baby. He is usually the first one to tell folks about the pregnancy. But not going to make a celebration at all.
Honestly the fact he does all of that for you I feel is his way of showing you he is happy about it. Everyone reacts to pregnancy differently and that doesn’t mean he is any less excited! He shows you every day he is. My partner has wanted a baby all his life and we got rather 5 years ago. Now at 41 we how our first on the way and he is so happy, okay he doesn’t sit and chat to the bump every day or even bonds with bump per se but he is dedicated to go to every appointment and makes sure he is there for me when I need him and even waxed my legs last night. That’s just their way it’s so much harder for a man because they are really connected to the baby until they’re born, I wouldn’t take offense to it and perhaps that kind of party just isn’t his style it’s not the same for men xx
To me he seems ready to have this baby with you. Maybe today wasn’t the day to have a party for him, it’s kinda a big day for some people and they wouldn’t have came even if he did invite them. Maybe try having a conversation with him about why he didn’t invite anyone.
