Losing a friend because I'm pregnant RANT!!!

Amanda • Happily married 💍 In love with my baby boy, Benjamin 💙
I guess now that I'm pregnant, my one and only friend blows off plans with me to hang out with her alcoholic/druggie friend?! That's cool.  We have completely different views in life and we are in different stages(I'm married, long term relationship, responsible, pregnant and mature, she is a party girl, in an on and off relationship, and has NO goals). I guess it's true when people say "you find out who your true friends are when you become pregnant". Did this happen to anyone else? I need to make mom friends! 😡 I'm so annoyed!
EDIT!: I'm not trying to bring her down, I'm just trying to explain how different we are in the stages of our life right now...
