If this person is Frum -then they have to get married whether they want to or not. It’s a Halacha. If they aren’t Frum -so who cares?
I hope you practice what you preach, even if it isn’t totally correct halachicly. She can wait for the right one, like Benos Tzelafchad (who were praised for not marrying less than 40, since their motives were good). If she says she never wants to get married and means it, that would be an issue.
