Distant partner

I’m almost 30 weeks pregnant and my partner seems so distant and not excited about our baby , we didn’t plan our baby but he had previously begged me multiple times to try for a baby with him and I always said no as for me a baby was never ever in my life plan

I’m so happy that I’m pregnant now and very excited to be a mummy but I’m finding it incredibly hard when he seems distant , a lot of the time he is great , rubbing my back kissing my belly and talking to the baby telling her how much he loves her , he’s also come to all my scans and midwife appointments and has agreed to come to antenatal classes with me but other times he won’t even help towards the cost of things and he says “ I never wanted a baby “ even though he told me all the time he did , he also says “ I’m not ready and you were the one who decided to keep it “

Those comments break my heart and for me his negative comments cover up all the positive things he says and does

How can I help him become more excited

I need the support as I’m very scared and nervous about becoming a parent
