Friend never congratulating me

I have this old friend of mine who has completely been ignoring the fact that I'm pregnant. She's never acknowledged it in ANY way. It confused me at first because I could just imagine her being excited in her goofball way about having a mini-me running around. And then I remember a conversation we had many many years ago about her truly believing in "overpopulation." She's a strange character. I think that's why she's never thrown a 'congrats' or a 'like' my way... 😒 It's sad. The only thing she acknowledges is the fact I have cats. I can't have a friend like that...
