A spinster, or old maid, is an older, childless woman who has never been married. A "spinster" is not simply a "single" woman, but a woman who has not formed a human pair bond by the time she is approaching or has reached menopause and the end of her reproductive lifespan
I fear Sarah-Jane is going to end up a lonely spinster with only a cat by her side for company.

An elderly or aging female who due to a combination of major personality flaws, undesirable personal habits, and unattractive physical appearance has never married. It is not uncommon for a spinster to have had many short term romantic relationships and to have spread her legs for many men. Females begin to enter spinster territory at the age of 35 or the first appearance of gray hair and or crow's feet.
Females often claim to be, "career oriented" or "independent" to help them come to terms with being a spinster.
