Friend (A) has asked me why I didn't invite her somewhere and the truth is, I didn't because she was down, some of it due to failed attempts at TTC. It was dinner with myself and a friend (B) and we both have babies of a certain age. Friend A and B are not friends otherwise and have no other contact unless they see each other at an event I invite them both to (not often but there is more to that). I was trying to protect her feelings now she's upset that she was excluded.
