The state of being single "forever". Applies both to those who simply can't seem to be able to find someone
to be with (involuntary permasingles) and to those who are
purposefully choosing to be single for any number of reasons, such as career, asexuality, etc. (
voluntary permasingles).
There may come a time when it becomes preferable to grab the bull by
the horns and choose to be permasingle rather than to allow yourself to get
devastated by disappointments after
disappointment with all the wrong people.
