Hi ECF,

Welcome to the forum.

I understand that you must be hurting a bit now, as losing someone you love dearly, with no control, is nothing short of depressing. I am not sure if she has PTSD though, as PTSD is a bit more than just pulling away socially and the aspects you have listed. I doubt that she got PTSD from her ex dieing, as she didn't witness it, however; depending on the amount of abuse she suffered from him previously, this could be something to do with possible PTSD. Smart move on sending her some literature, just to cover bases and possibly get her to move herself to some help.

I would say that she nees counselling now... ASAP, to ascertain exactly what the issue is, because she is bottling it all up. When one bottles it up, is the point where PTSD begins to stem, and if formed, there is no return if she has it.
