I was single until aged 47. But I did not crawl under the bed and bemoan my lot!
Having flown the nest in 1976 at a very old age of 23, and setting up my own home, I began to enjoy my new-found independence, free from parential restraint. I have always loved travel, (my first independent trip out of the UK was to Spain in 1972, aged 19) and I backpacked Europe, that is Italy (my country of origin), France, Germany Holland and Belgium along with Israel (and how I love Jerusalem Old City), Canada (Vancouver to Toronto), the United States, Singapore and Australia (Port Douglas to Sydney)
Actually, the more I travelled, the more I wished I had stayed at home with my parents. Staying at backpackers hostels, I met people who spend maybe up to two years working and travelling (one was an Irish builder, another was an Aussie builder, whom I chatted in Israel and San Diego respectively. Both said to me that their home is with their parents, and I have spoken to others who said the same.
Sorry, I am rabbiting on something I have such a passion for. Please excuse me for that.
My point is: Your life is how you make it.
You can mope around and bemoan your fate. Or you can make your single status into something useful, memorial or just adventurous.
Having a partner is much more that sexual attraction. It is a committment for both. For a partnership to work long term, sacrifices would have to be made. In my case I gave up much (but not all) of backpacking.
I no longer look after number one. Instead my soulmate comes first.
But being together to us is much more fulfilling than being on my own. But for me this took a long time. Looking back, I now realise that I was not then personally mature enough for a long term relationship.
Enjoy your singleness while you have it. Carve out a personal story you can relate about. Then when you find someone, you'll have a story to tell.
