If it is okay to abandon a spouse with Alzheimer's because we lack the "capacity" to live with someone who has that particular disease, or because it is financially difficult, the "intensity of their love", or any of the other reasons you gave, then wouldn't it be okay to abandon your spouse for ANY reason? Maybe I have the "capacity" to live with someone with a broken leg, but not diabetes or cancer? No, I don't have that "capacity". (Because...wow...that would require more on my part and why would I want to do more?) Or we should abandon a spouse because their illness is expensive? Or abandon them because we have "intensity" of love for the easier illnesses, but not the tough ones? We should abandon them for eternity simply because things got a little difficult in the mortal life? My husband died two years ago Sunday. He had health issues for a number of years. They started even before we were married. He had a leg amputated just a few months prior to our wedding and died just before our first anniversary. I guess I should never have married him and I certainly should have abandoned him when his health took an unexpected turn - a terminal turn - after our marriage, especially because his mind started to go as well. I guess I could have simply said that I didn't have the "intensity" of love or the "capacity" for something THAT hard, but hey, give me a husband with a broken leg instead and I will stick around. I was diagnosed with MS after he died. But I guess if he had been alive and healthy, it would have been okay for him to say..."I love you, but not THAT much, I'm outta here". I don't see how it is okay to abandon a spouse in their time of need, just because that need might cause some inconvenience or hardship for us, or some ill-defined unhappiness.
