I am aware she is renting from her parents but you did say that arrangement will not continue. So, yes, she will be needing a new place to live be it an apartment or house.
Did you ever consider maybe she was sharing her "good news" in order to have a reason to ask you for assistance if need be? She made herself look wonderful... look at me, I took a huge pay cut despite all my great offers and I will be paying the insurance BUT since I did all this you may have to help me out.
Sorry, that is how it reads to me. She never shared anything with you in the recent past because she did not need anything. Having been on the receiving end of this for 22 months with my own H I am familiar with the routine.
