Is there a term when a woman can NEVER get commitment from any man?

There are certain women 30+ years and above that actually have never slept around, are family-oriented women, they had 2-3 long-term relationships but can't get commitment from a man. They just can't ever get a man to propose to them ever.

Is there a term for that, for a woman that never slept around, lives a healthy life but yet can't ever get a marriage proposal? My aunt (mom's older sister) couldn't ever get that and she's not a modern woman type.
