Gender disappointment

Can’t get used to the fact that my husband and I are having a boy. This is our first baby and hopefully we will be able to have more kids in the future and will have an opportunity to try for a girl...I am just not sure because I have some cardiac issues and if this pregnancy will be tough I am not sure if I will want to go through all of this again. The thing is my husband has a girl from previous marriage. He loves her so much and he has always told me how he always wanted a daughter and how he was happy that it was what him and his ex wife had. He also told me he wants us to have a girl and when I asked him about a boy he said that it’s okay but he isn’t very excited about a boy. A girl is what he really wants. And I saw him treating his daughter like a little princess which melted my heart and I always imagined us having a girl and him being so sweet with her as well...but we are having a boy. 😔 I could tell he was disappointed when we found out. He tried really hard to act like he is not, but I feel he is. Ever since we found out he has been talking about us having the second baby and it being a girl...but as I said before I am not sure if I will be able to go through another pregnancy due to health issues. I am now heartbroken. I feel sad every single day. His parents also say that ooh we are so sorry. You’ll have a girl next time. They also said that men love girls so much more than they do boys...wth!!!!😭Please, don’t be judgmental... I really need some support.... I feel alone with my baby.
