I have been in your position. My friend had been TTC for 3 years without success when we started TTC. Soon after we started trying, she started IVF. It took us 9 months and she was still TTC on IVF. She said she was happy for us, and she had many other friends have babies before and after us, but she did stop talking to us for a long time. When DS was born she didn't acknowledge him at all. She only started speaking to us again when she was pg with twins (who were born in Feb). I can understand it must have been difficult for her, but it's hard to be shut out through no fault of your own. Hopefully your friend will come to terms it sooner than this and there will be no harm done. I am not sure what advice to offer, I guess just to try and guage how much you should talk about it with her so as not to be in her face but also not exclude her. Perhaps asking her would help?

Good luck,
Melanie
