One may have the perception of loneliness when one is alone. This may be applicable for one who has been constantly with somebody. Such circumstance does not give one much opportunity to be alone. The transition is challenging at first when one does not longer have somebody to talk about the daily happenings of life. There is nobody to vent one’s feelings to. There is nobody to spend special holidays with. One is likely to become introverted and the need to be with others is likely to diminish as the time passes. One becomes really comfortable with oneself to a point he/she prefer it.
I am one of such example. I can attest the benefit of being alone and this allows me to understand myself better and more aware of the existing circumstances.
There is another fear of being alone when one grows old. I used to have such fear in the past. However, I made peace with the possibility of living in a senior’s home to meet lots of other people in the same stage. If company and safety are my concerns, such arrangement will solve the problem. Nobody can guarantee a partner or kids taking care of oneself in old age. Previously, I found this notion to be really depressing. However, I see it as a backup plan, and it is oddly comforting. I do not rule out living in a cruise. There is an example of a lady in her 70s who solo travel and swims a few kilometres a day. There are also people who skydived in their 60s. Some retired and live in the recreational vehicles. There are limitless options for one to choose.
When this fear of loneliness goes away, the need to settle also vanishes. If I find somebody (with the common wavelength), such relationship will be great. If no, life will be nice as usual.
