Help me understand how to respond to my friend who cut me off after my pregnancy announcement

My (30s) best friend (30s) has been trying for a baby over the past year. She fell pregnant and found out she has a rare genetic condition which means her pregnancies run the risk of being unviable 20% of the time. Sadly the worst case scenario happened at 13 weeks and she had to terminate the pregnancy. She’s been trying since (the past 7 months) and I started trying around the same time.

I told her last week at the 8 week mark. I posted previously about how that went and I think in retrospect I should have told her over text - but now one week later she has texted me saying she can’t be friends with me anymore as it is too hard for her to have a pregnant friend

I’m so hurt. I know it must be very difficult- but she is my best friend. She was my maid of honour this summer. Her and I are like sisters. I live abroad and don’t have a lot of friends and I would say she is my only truly close confident in this country. I really don’t want to go through this pregnancy without her friendship. I love and need her.

Idk how to respond. I don’t know what to say.
