Found out sex of baby on my own 😁

NAtasha
My bf didn't want to know so half way through he was asked to leave and they told me I'm having a boy. I thought girl all along so now I have until January to keep it from him he thinks it's a girl as I came out happy but I've bluffing him. I'm a bit upset although happy. As he only wants one baby as has a son already I feel like although I'm having a boy I'll never have the girl that I wanted and thought it was. Anyone else felt this? I've read its natural tried explaining to him how id feel either way without telling him and he said silly to miss something u never had.....I had room planned clothes everything lol. I am over the moon I have a little boy but I wanted a girl as he has a son already and I won't experience this. It would have been nice for him to have a girl to. Anyone think I can change a mans mind from a form no to maybe another in future....sorry long post I'm the only one who knows sex and u
