Jealous family members?

My favorite cousin is also pregnant and being awful. First, she criticized me for telling people about my pregnancy before 12 weeks, which I thought was weird since it's none of her business but I let it go. Then, she criticized me for not noticing that she is pregnant. Mind you, she didn't announce the news to me or my family. I saw her pics on Facebook and thought she was looking plumper but she's still early on.

Then, she got mad at me for not gaining as much weight as she has, even though I gained quite a few pounds and my doctor says I am right on track.

But then, she ruined my gender reveal by being passive aggressive. She told me I am a bad person and a bad mother for announcing my baby girls name before the birth. She told me that my baby is now cursed and I will have a still birth!!!

I think she is jealous! But I don't know why! She is a gorgeous French woman and has a model husband! 

Sorry for ranting so much, but it helps :P
