Long time friend (not)

I don't know if I'm being fair but I feel betrayed. My oldest friend always told me she didn't want babies. And then I've found out she was five months pregnant and did not told me. We were best friends for so many years. I feel sad she didn't share those great news with me. And also found out that while she was trying to conceive she kept telling me she didn't like kids. Why would she do something like that? I feel like I don't know her anymore. She's almost due, and I wish her all the best in the world, but I don't want to be with her and she doesn't try to contact me. She choses to be with the friends she always said were forcing her to be a mother.
