I completely understand what you are saying and earlier tonight, when W brought up her parent's mortality again, I did offer to be there to help her through the process in whatever way she choose. She got silent on the subject, said thanks, then we ended the phone conversation.
Not too long later, she began playfully texting me about what D was doing tonight and even asked what I was doing and if I had a "hot date." After that, she started in w/ R questions and we've been going back an forth on that subject ever since.
So, maybe your suggestion to her that I'd be willing and able to help her out and support her when the time comes for her parents to pass helped my situation out as well.
