As a caregiving spouse for late moderte Alzheimer's patient, there is now a terrible loneliness felt in all aspects of our relationship....what are the moral and ethical issues concerning my seeking and starting a new relationship with someone else....this would be after 50 years of absolute faithfulness to our marriage and would still be there for her until such time as alternate full time living arrangements become necessary.
The man visited his wife every day at the NH, talked to her, fed her and read to her. The response was silence. Finally the man gave in to the wishes of his girlfriend, and divorced his wife.......still visitng every day, feeding her, talking to her silent body. Carla convinced him that his visits were useless, unncessary. He and Carla did marry. On the evening of the marriage, he received a call from the NH that his wife had passed away, leaving her ring around a rolled up piece of paper with their photo tucked inside. No one on the Nursing Staff ever remembers putting a ring around a rolled up paper with any photo.
"to be faithful through sickness and through health..."
Having extramarrital affairs? Whoever your "New" companion is, she will remind you of what "Normal" used to be - to talk to someone, to laugh, to share the current news, to enjoy everything that you no longer experience now. Your heart will soon follow your..uhm...desires (sorry, trying to be political correct here). I think you're fooling yourself if you think you can just have extramarital "activities" and NOT have it affect you and the wife.
In the end, you will resent your wife for holding you back, for wasting money on her when you have better use for it, etc... I'm sorry...
I believe in God, the Bible and marriage. I cannot condone extramarital affairs. Your marriage vows did not have an exclusion clause on it.
The other thing to consider it is that there is a difference between a friendship relationship and romantic/sexual relationship. Some would say the friendship is ok, but not the sexual. The problem is a friendship turning into something more.
If you don't already do so, you might want to consider social activities, not couples activities, or finding people with the interests/hobbies, and it would help the loneliness.
