No one is excited..... but me

I get the vibe that none of my family is excited for this new baby, only because they dislike my BF. My sister has two kids with a guy they don’t like and they’re all over her. I have only told my mom and two sisters and they act like they don’t give a sh*t. Now I’m to the point I don’t want to tell any of my family because of how they’re acting. I can’t be excited because they want to be negative nancies.. I’m just over it.
