My husband seems uninterested in my pregnancy

... and it’s really starting to upset me. I am 17 weeks, and he was super excited and attentive to me the first 5-7ish weeks and ever since he doesn’t ever bring it up. I am the one talking about how I’m feeling, bringing up baby, and acknowledging that I am pregnant. He doesn’t ever ask how i am feeling, if i need anything, talk about being pregnant or anything. It’s starting to scare me for when the baby gets here. I already feel isolated and alone. 😔😥
