What happened to Jenny in Forrest Gump? There is no introduction in the play. Does Forrest Gump's son have no influence?

In the film, Forrest Gump, with an American southern accent and mental retardation, stares at Jenny, who is full of wildness, as if she were distant relatives with Benji, the fool in Faulkner's masterpiece The Sound and the Fury. But there are obvious essential differences between them: Bangui is only a symbol of family decline and a real imbecile; Forrest Gump, on the other hand, represents almost all the virtues lacking in this era: honesty and trustworthiness, earnest work, courage and fearlessness, and attaching importance to feelings over wealth. On the other hand, having these virtues makes you stupid, which is really a great irony to some social situations today.

Jenny Forrest Gump loves is a symbol of depravity. She caught almost all the bad habits, such as drug abuse and sexual liberation, and finally she died of a virus-in fact, this refers to HIV. But Forrest Gump loves her desperately. The film not only makes specious accusations against him, but also shows his innocence and kindness.
