I think in reality you are going to find it very hard to consider this friendship to be in any way meaningful after this.
There are very few times in our lives, thankfully, that we will be in such pain, and we need the love and support from our friends. It is not so much to ask.
This is not about her pregnancy, this is about the complete absence of support from her during what has to be one of the worst moments of your life.
Sending texts, calling you to check on you is all she had to do. The idea that you needed ‘space’ or she had to discuss her news with you is a red herring.
She knew she should have been there for you. Even now she has failed to acknowledge this, blaming you and your loss for her lack of contact. She hasn’t apologised or even explained why she failed you so dismally. Had she done any of the above, you would be in a much better position to move forward as friends.
My friend had a miscarriage, she guessed I was pregnant a few weeks later, we cried together, we hugged and we spoke only of her pain for the next six months it took until she was pregnant again, why? Because I could share my news and excitement with everyone and anyone else, I did not need or expect that from her.
She came first, because her pain and need at that moment was far far greater than mine. I refused to talk about my pregnancy at all with her, and we got her through the darkest moments together. It didn’t lessen my pregnancy or change how I felt about it, but it did make it bearable for her.
We are still friends today.
Sometimes we need to know when to put our friends first, when we need to step up and pick up the pieces - when they need us most. We have to be there - otherwise what the hell is the point in being friends at all ?
