Im a little mad, but mostly annoyed. Over reacting?

Nicole • Wife, and mother to a beautiful baby boy 💙💙 3.2.19

So i had a best friend... a long time ago. We fell out because she was pregnant & lost her sister while i was going through an abortion ( took me a LONG time to get over this, please no judgment i think i judged myself enough over that decision and unfortunately i cant change it).

We both felt like we weren’t there for each other even though she mostly blamed me for everything. After about a year of not speaking I truly apologized and honestly wanted to bury the hatchet and possibly try again, she STILL blamed me and took no responsibility.

So i gave up, she had her baby, and in the meantime i got married, and now I’m 12 weeks pregnant. We do not have mutual friends with the exception of a few Facebook “friends” none of my coworkers (which are in turn her ex coworkers) speak with her, and i have not posted anything on Facebook about being pregnant. So I’m confused as to how I received a congratulatory message on fb from her.

I am petty and still hold a grudge because i hate unfair people, and people who cant own up to their mistakes. As you can see by my clipped response 🤦🏽‍♀️🤦🏽‍♀️

Im just trying to figure out who told her & why. Am i over reacting? I really feel like if i wanted her to know it was my right to reach out. This is really bothering me.
