I agree with you OP, I also wonder why many women are afraid of being on their own. I have known a few friends who, after gaining their freedom from disastrous relationships, have been absolutely desperate to pair up with someone...in some cases, picking unsuitable partners and moving in too quickly, just because they don't want to be single (and of course, making mistakes all over again because of it).
I assume it is more about company and companionship, and a lack of being able to enjoy solitude, rather than financial issues. At least, I hope that's the case, as it would otherwise mean they are finding partners purely for the extra money??
I was married for 21 years and had a couple of short relationships after that but soon concluded I loved the freedom of being independent. I just don't want to have a partner again, I never want to remarry and never want to live with anyone these days.
I think I have more friends now than in my earlier years....female friends, male friends, couples....
But I enjoy the freedom to live where I like, move when I want to, change jobs or do something entirely different without considering anyone else. I have masses of hobbies, go out to places, travel a lot....all things I could never do when I was married because I had to factor in someone else all the time. I have a very full life but don't fear quietness or solitude (in fact, I rather enjoy it) and don't fear being old and single (quite frankly, I think it will be easier without someone else to consider). If I become infirm or entirely demented, I shall happily succumb to the nursing home.
I do accept, however, that for those on their own with young children still at home, singledom is much harder to manage.
