3rd boy and feeling sad

I feel so selfish and I know I should just be happy we have a so far a healthy baby but... Just found out it's boy # 3 for me. I'm such a girly girly myself and really really wanted a girl. We did a big reveal party tonight and I smiled and had fun but now that everyone left I can't stop crying. My husband is angry because he's excited and now feels like he can't be because I'm so upset.  Anyone else feel this way? I wanted my girl so badly it hurts
