fiancé is upset about gender

Lauren
So today we had the chance to find out the gender of our baby. Please keep in mind, we have been waiting 3 years for a baby, have two babies in heaven and went through countless fertility treatments. My fiancé is the last one to carry on his last name.. we are only 25 &27 with lots of time to make babies.
So we found out we're having a girl. As for me, I cried my eyes out because either way I was happy. He on the other hand took away my excitement and mad me cry because he was upset it wasn't a boy. He won't even talk to me, look at me or anything. He's making me feel so guilty. He's using the excuse he has the "gender baby blues" and it won't go away until the baby is born, Some doctor said. We went and told his parents and they made him feel like less of a man because it wasn't a boy. Everyone on his side of the family is acting like this is a disappointment. But my family is just happy I have a healthy child, after so many years. I'm just at a loss for words, what do I do? I think he's being completely selfish and took away such a special moment for me. Like I can't even be happy or he'll love the baby less since it's a girl. I understand he's the last one to carry his name but I mean come on, we're still young.
