I've been single myself for almost 15 years now. For a short time I tried to find a mate, was desperate to find a mate after the death of my hubby, with whom I did not have a good relationship. Why did I want to replace him? I do not know. I did have one longish relationship, 2 years, but it went on for quite some time after I found him very troublesome to have to care about his wellbeing and happiness; my three kids were plenty of stuff to care about., and my desires to see them happy were genuine. The dude was married six months after I broke it off to the first woman who would say yes.
At this age (advanced), the single women are no longer interested in marriage, but the men seem desperate for it.
I no longer care. If someone does come along whom I cannot wait to be with, I might reconsider. But as it is, anyone I do date, quickly becomes a burden whom I have to squeeze time in with. I'd rather be caught up on my laundry and bills.
I haven't been single that long but the way things are now and how genuinely pleased I am in a general sense about all aspects of my life I can't really see any issues that I would have if I were to be single for 15 years as well.
