Maybe some time apart might not be a bad thing? A chance for her and you to cool off and get some breathing space. Then when you are feeling stronger and happier maybe you can ask her if she wants to meet for coffee. Tell her that you miss her and if possible try and make her understand how you are feeling about TTC and your miscarriage. No one understands what we are going through, the only ones that do understand are the ones that have been through it. So she will scratch her head and do her best to understand.....but really she wont. She obviously cares and worries about you a lot, she is probably feeling sad and probably a llittle hurt about your reaction - even a lilttle embarassed.
I also have a friend that can be incredibily blunt with me re TTC. She tells me on a regular basis that "there is more to life than having a baby" like I am a freak with wanting it so bad. She has had two years of TTC with no luck and things are not looking so good there.....so of course she is speaking more about herself when she spits that in my face. For me right now there is nothing more important than having a baby. In fact, I feel physcially sick at the thought of never being a Mother. So now I dont discuss it with her so much or when I do I make sure I am feeling strong so I can deal with her firm opinions.
Dont lose your freind over this, give her a big hug and say sorry - let her know that you want to talk about other things right now.....but when you are ready to talk about your m/c she will be the first one you do open up to.
Take care
