So heartbroken. I finally found out I am having a girl today and after sharing it with the kids (my SO was with me today) I shared it with my FB. I have family on there that I hardly see so it is a way for me to share it. Every one is so excited for me so I was even more excited and then my SO text me pisses asking why I shared it because he didn't want his family to know. I am just at lost as to what to say really. His family sucks honestly and I only have 2 of his family members on my FB but they like to talk. I just was so excited and now He ruined my day.
