My advice is to continue loving her and if she does not want to engage, I am sure you will get a signal. If she can still do her personal care and other activities then as a woman I would say she enjoys the loving contact. Speaking as a woman close to her age. I mean you might be feeling guilty, but please don't. Just continue and enjoy each other while you still can. All my best to you both.

....Of coarse in today's overly nosey and litigious climate, it might be prudent to consult a lawyer and see if there are any existing statutes that need to be taken into consideration
