no support from "best friend" during my miscarriage.

My best friend of 15 years and I have always been inseparable. We both recently got married and were each other's maid/maitron of honor. We tell each other everything. We've been dreaming of weddings and babies forever.  We do everything together, even after being married. That's why, last month, when I got my first BFP ever, I called her IMMEDIATELY after celebrating with my hubby. She was ecstatic! She was already talking about gender reveal parties and baby shower parties. The next day, I miscarried. After my husband, she was the first person I told. Through text, she was very sympathetic and making sure I was ok.  No phone call. No visit. Not really much more than a text. Meanwhile, multiple other friends of ours that I'm not HALF as close with cane by our house, had flowers sent, etc. To this day, I haven't heard from her or gottten any follow ups or check ups from her. I just feel so disappointed  and let down by her. It's not that I NEED her emotional support. My amazing husband and family have been the best support in the world. But... I just expected my lifelong best friend to act like she cared a bit more... I've tried calling her . No answer or call back. 😕
