I am not married either, but seem to be quite thoroughly self-sufficient.
As to why, well... I kind of get the feeling that an awful lot of possible responses might come across as misogynistic. Perhaps that feeling in itself is part of the problem? Like, what if just as many men used to live in a state of "perpetual adolescence" (people were certainly writing about such things as far back as 1983
), but women were more willing to put up with them due to societal pressure? (Not to say that anyone should
have to put up with that. Far from it.) Or maybe it's completely stupid to generalize about what "men" and "women" are doing at any particular time.
It's just that I hear so many tales of people - both men and women - whose lives have been utterly and completely devastated in ways that nothing else can compare because of one failed relationship. To which the obvious response is that a successful relationship can be equally as rewarding and entirely worth the risk. I suppose I have trouble conceiving of something that can be that rewarding. Or maybe that's just what I keep telling myself.
