I just might do that when my boat goes down. Right now we've just taken on a lot of water. But I am a realist and see what is coming.
I think it is good to be a realist and prepare yourself mentally and emotionally as far ahead as you can. I did not do that so I experienced a sudden shock. On an unconscious level maybe I knew but I did everything I could keep it out of conscious awareness. I think we all handle such circumstances according to our particular circumstances and personality. I have always had to use avoidance in order to manage my anxiety so I could function in everyday life. It is quite a balancing act.
We still take a walk together every day and eat two meals together most days. She is an artist and though she has doctor appointments (or physical therapy or meets with a dietician) most days she puts Wednesdays aside for the studio and has a friend who works for her those days who is also an artist in her own right. She is currently in two shows locally, one in our town and one in Marin county. So she has a kind of structure which I think she enjoys too. I maintain and am always adding to a garden that is already too large given my growing list of mobility challenges. Except for what I can reach with my six foot orchard ladder I bring an arborist for anything higher up. I find I am quite content being well and truly retired. I read some in Iain McGilchrist's 1500 page tome The Matter With Things everyday and when I finish with that I look forward to getting back into reading good novels - something I considered a trifle when I was still teaching but now realize can be very special.
It doesn't sound like your boat is going down any time soon but I will be here if and when it does. My late husband was not active doing anything for years before he passed. He started to go downhill emotionally when he retired in 2016 but it was so gradual I was not alarmed, and he would never admit he as depressed although in retrospect I think he was. Then when Covid came he got much worse, refusing to even leave the house. After a while he started to eat less and less so it was a battle just to get him to eat one meal a day. The doctor was not as alarmed as he should have been about the weight loss since he did not have any medical conditions except chronic asthma, which was managed by medications. He was not diagnosed with cancer until about three months prior to his demise, he was misdiagnosed as having prostate issues and urinary tract infections. I think his whole case was mismanaged so I will be filing a complaint with the HMO and possibly also filing a lawsuit since that is the only way I will ever know what really happened. However, part of the problem is that he had no desire to live so he just stopped eating but the hospital allowed him to make that choice.
I am active physically, exercising two hours a day, but I don't have any other outdoor activities such as gardening or yard work. With having to care for my husband and the house and deal with my two rental homes and eight cats, as well as working full time, I never had time for hobbies. I do spend a lot of time on this forum because I need a social network and a sense of purpose, and I like that I am always learning from others.
My wife and I moved into separate bedrooms a few years ago as waking each other up became more and more irritating. I'm an early riser, am in bed by 8 and want the light out by 9. She rarely goes to sleep before midnight and likes to go to sleep with the television on. Plus both of us have to get up to pee multiple times in the night. It is annoying enough when one has to wake up enough go themselves without also being woken up by the other doing so. This is so much more sensible. We can either one visit the other conjugally but there isn't a lot of real interest there on either side anymore. Still the companionship is great and I honestly don't know how much company I will want once the boat goes down. Before we got together I found that I'd spend a whole lot more time and energy putting myself in situations to socialize and meet people than I'd actually spend doing with a partner. So partnering up made more sense. Of course my libido would have provided a lot of the impetus for that back then.
My husband and I slept in separate bedrooms ever since we moved into this house in 2009. I slept downstairs with the male cats and he slept upstairs with the female cats since we had more cats back then and we had to keep the male cats separate from the females. But by that time we were not intimate anymore anyway. Eventually the three male cats that had not passed on were brought upstairs since they were sickly and I started sleeping upstairs, but he kept a completely different schedule after he retired so he usually slept in the living room in the recliner watching TV. Even though we did not sleep in the bedroom together for very long I cannot sleep in there now so I bought a daybed and mattress for the living room. I do not expect I will go back to sleeping in that bedroom ever again. The cats like it though and I need the space for them.
I was very miserable when he was alive for so many years, as long as I can remember, not because of the relationship but because he was so depressed and he would not take care of himself and I was at a loss to know what to do. I also had other things going on with cats being ill and dying constantly and constant problems with the rental houses. Now I don't have any of those problems so an objective observer might wonder what I don't feel better. But there is a lot more to it than that. The hole I feel with him gone is with me constantly and I don't think it is going to go away, so I just have to learn to live with it. I don't think anyone knows how they will feel or what they will do until they find themselves in the situation.
I admired my father in law quite a bit. He and my mother in law were nearly the same age and they retired to a beautiful place and kept active for a long time. He always planned for her surviving him because women by and large do. But she who always ate and cooked healthy meals died at 80 of a congenital heart condition while he lived on into his mid 90's. Talking about what he missed most he said it was just having someone to tell what you saw on your walk each day.
My mother and father were the same age but he died at age 53 and she lived to be 93, in spite of smoking and drinking for most of her life.
One never knows what their fate will be. They can plan things but so many things are out of our control, especially disease and death. Some people are just lucky, like my neighbor who has been married over 50 years, as both he and his wife are active and in good health. However, that luck could turn on a dime. I posted a thread about that once.
I have never planned for anything, including getting married. I did not plan to go to college, buy houses, and now I am not planning for retirement. I live fully in the present, and that is how I manage not to get depressed or anxious. I never think about the past unless I am talking to someone about it, and I never think about the future, since I don't have anything to look forward to except more of the same.
