If I am 60 and broke, well so be it. That is life.
But if I am 60 and well off with plenty of money and family and am miserable, than there is absolutely no point in living it.
We cannot predict the future. Tragedy strikes all the time. In no way am I trying to be insensitive, but who is to say, hypothetically, I had a husband and he dropped dead of a heart attack at 50. Him being the bread winner, where does that leave me?? I'd be up the creek without a paddle, and no support. Who's to say he doesn't leave me for someone else? It happens all the time.
By providing for myself, I only have to rely on myself. That provides me with a lot more security.
I have friends and supports all over. In the last year I have had to deal with some big challenges, mostly on my own. I am getting through them. I have proved to myself that I can do anything. I don't need romantic attachment to get through the challenges of life.
This is my personal experience and I know several other people who have similar experiences. I know a woman who has just turned 90. She is still living alone, with family who rarely visit. She is doing very well.
I am happy and content with my life and where I am at. I do not need companionship, I do not seek it, and I do not want it! Nothing anyone says or does is going to change that.
