I have two very close friends who have been TTC for 5+ years. One is still waiting, another is in her 2nd pregnancy. Both have had tough journeys. Anytime we have experienced a pregnancy, they pull back a bit, and there is no way we would be upset by that. Actually, we are a bit hesitant on how to break the news sometimes b/c we are sensitive to their journey. It is completely understandable to react however you need to stay positive for you in the long run, and true friends will get it. I've also had two losses and both times, both of my TTC friends, were also supportive.
