WIBTAH for messaging a friend that cut me off after 2 years?

So this is a whirlwind. Background: My friend A (F 29) and I (F 27) met in college. We got closer when she dated and eventually married a childhood friend of mine (M 27). We were close enough, I was in her wedding. After we all finished college, we moved back to mine and my childhood friend's hometown. We all attended the same church and hung out when we could. The day I had came home from the hospital with my newborn son, they called us telling us they were expecting. This is all background for the actual story and question.

After their daughter was born, we didn't hang out as much, but we were both new parents; it was understandable. They starting missing more church as well, but it was the height of sickness in our area, so again understandable. At this point it had been over 3 weeks since I'd seen or heard from them. I was checking Facebook and noticed that A had popped up on "People you may know", which was weird cause we were already friends on Facebook. I assumed that while I was scrolling while feeding my son, he had accidentally clicked something, or I dropped my phone. I just assumed it was an accident. So I sent a new friend request. The next time I checked I was blocked. Again, I haven't talked with her for over 3 weeks. So I texted her just saying "Hey what's up?". That's when she said that she blocked me because her and her husband decided to leave our church, and she knew I was stalking her because I hadn't liked her posts in awhile, and saying all sorts of things behind her back. Extra context, I'm a teacher. This happened at the beginning of the school year. On top of that, my husband was dealing with some health issues that landed him in the hospital. When I received this text from her, I was floored. I assured her that I was just busy, and I had not stalked her or had any intention to. I also had no idea she had left our church. She really didn't care, and said she was done with our friendship. This happened 2 years ago.

Fast forward to now. My sister showed me a post that A made, talking about something awful that her brother had done and how she no longer had contact with her brother or mom. As I read the post, I realized it was very similar to my own story. I also had a brother who did the same thing. I got upset as I had worked with her brother and had I known what he had done, I would have stopped and told someone. And now she's cut me off and we can't support each other with this burden.

Now comes my question, WIBTAH if I reached out? She has cut off other friends that she has been slowly adding back in her life. But I also don't know if I want to bring her back in my life. Should I tell her my story? Should I try to have a connection? Or should I just let her be? I'm just not sure.
