I have lived alone for the last 20 years and could not imagine having to share my life with anyone for any length of time. I enjoy having family and friends to stay, but find a short time is enough. It is so good to be able to read without feeling guilty. I also travelled a lot on my own and the great advantage of that, was that I always manage to meet local people and learn much more about the countries I have travelled to. This never happens when I travel with friends. Unfortunately, these days are now over, as insurance costs are too high. Take every opportunity while you have the chance.
