Should I?

My best friend of 4 years has been there thick and thin during my TTC times and I’ve been there for her during the ups and downs of life and her wedding planning, enjoyed every single bit. This year going on 5 years of being friends, I had found out January I’m finally pregnant! Expecting my first baby, a girl 💕 at first she told me how excited she was for me but I began to notice a weird distance and about 3 days go by, not much talking but then we hung out and she got into my car and broke down crying about how “sad” I’ve made her by getting pregnant (she said this) and that she wishes her husband was ready for kids too. After that, our conversations dwindled, we don’t talk, we don’t text, and I’ve began to blame myself for it all. My question is, I really want to text her and just say can I know what happened with us, should I? Or should I just let it go? It eats me up a lot, I feel so lonely and like I’m the problem and I finally want to know what the heck happened.
