I don’t understand the Jenny hate. Did they expect her to stay with Forrest and wait for him at home just baking pies and listening to the radio while he went off to war, sailed his shrimp boat, toured as a ping pong champion, and then just fucked off to go running for two years?
Gump and Jenny were both rolling stones. She wanted to be free, and fly far far away from the home where she was abused. She wanted her own adventures. Gump was her best friend, but she didn’t have the capacity for the relationship he wanted.
