A nineteen-year-old girl?

How do you say this kind of thing? Mother will definitely regret it, but I'm afraid she abandoned her daughter for a reason. For example, the mother herself is not sensible, and her father tricked her into getting married, or forced her to get married. He is probably a teenager himself, so he can't live with his father before he leaves. But it is precisely because of these experiences that the girl has worked hard.
