“Best friend” abandoned me during pregnancy

Back story, I’m currently 35 weeks pregnant. I have had 4 miscarriages, staying pregnant is very hard for me so this baby is such a blessing and so so wanted.

I’ve been married 8 years. Husband is so excited too.

My best friend/cousin is 5 years older and single but we have been like sisters and the best of friends for over 15 years. I live about 2 hours away so when she came to visit me in early September I told her that I was pregnant. At that point I was taking meds to help sustain the pregnancy and was very reluctant to share but couldn’t hide my morning sickness (all day sickness really). When I told her she cried. Went silent for 2 hours while she drove around back roads in my car. I was taken aback (and almost felt embarrassed because she acted so poorly. Anytime she shares good news with me about her life I congratulate her and I’m super supportive so I was really upset she couldn’t even fake it.) She went home that night and has barely spoken to me since. I invited her to gender ultrasounds, baby showers, drs appts etc and she always has an excuse not to come. But will text me for menial things like “why didn’t you text my mom for her birthday today” and when I tell her it slipped my mind she says “I figured” and acts offended but has never once remembered my parents birthdays? She will text me sometimes about random stuff but hasn’t mentioned my pregnancy once and hasn’t once asked how I am or how my pregnancy is going. The past two weeks she’s been traveling for work during the day so she’s been driving a lot and wants me to call her at weird times during the afternoon when I have stuff going on. She only ever wants to talk to me when she’s driving somewhere. Still not mentioning the pregnancy. I’ve been so hurt by her lack of caring about me during this super vulnerable time that I have stopped prioritizing her want to talk and sometimes find myself making excuses that I’m busy when she tells me to call her.

How should I handle this? If I bring up the baby at all she just ignores what I say and changes the subject in a very obvious rude way. Would you end a friendship over this?

EDIT: Two of her other friends are pregnant currently and she has bought them gifts, flew across the country for gender reveal and baby showers and has shown them nothing but support. She even ASKED ME what the best shower gifts would be FOR THEM.
