Take a look for yourself.
I am reminded of a story I saw on Sandra Day O'Connor, whose late husband John was diagnosed with Alzehiemer's. In his state of dementia, in which he no longer recognized his own wife, he struck up a romance at his skilled care facility with another woman. Although she did not appear in the story that ran, former justice O'Connor was reported to be pleased that her husband was comfortable and happy.
That's love, not dumping your wife because she's no longer of service or entertaining to you.
