Respectfully, I think you may have missed Bill's points. Or maybe men are more loyal than women. I'm the same as Bill, but a couple of years behind. In fact, my wife and I were divorced, and when she was hit with this monster, I remarried her so I could care for her.
I didn't read into it that Bill wanted to present as a martyr; in fact, just the opposite. He gave numbered reasons, and very well thought out, I might add, that he still has the love of his life at home with him. He has empathy, as if he were her; how would he feel under the circumstances( if he were her and she were him)? I don't want strangers cleaning my wife up. I don't want her to be embarrassed or handled roughly when she's being changed. I am the best care she can get, paid or unpaid. Placing a loved one in a facility so "I can live my life" WHAT? Like Bill, I still work full-time, but remote now, so I can care for Karen. I have an aortic aneurysm, COPD, two knee revisions, and five eye surgeries that left me blind in my right eye. I'm not a martyr. She's my wife! That's why I care for her.
We each have to make our own decisions, but best not to work out our own decisions superimposing the underlying reasons on others as if their decisions are less than what they say.
