My boyfriend wanted a boy...😪

the whole time I’ve been pregnant my S/O has been talking about having a little boy, when he would talk about the baby he referred to it as “he.” On Tuesday we found we’re having a baby girl. I’m beyond excited to be a mommy to this little girl but my boyfriend just seems upset, almost like he’s disappointed. He doesn’t want to discuss the baby at all and it breaks my heart. I want him to love this little baby as much as I do. I was a daddy’s girl when I was little, I had the most amazing dad and I want my daughter to have what I had, unconditional love. I’m hoping he gets over it but I don’t know...what should I do?
