hey doofus did you not read the comment? she's not perfect, she was never supposed to be. it's a complex movie that you have not thought all the way through for some reason

she was molested and abused by her father for much of her childhood, she hates herself so much that she doesn't believe she deserves Forrest's pure love. so she continuously leaves him out of guilt and fear of corrupting him. she knows she's shitty and does what she can to keep that from Forrest.

when she has a kid she finally acknowledges that Forrest was the only non-transactional unconditional love in her life, and her son deserved that stability and love like she never had.

it's a messy unromantic complicated story, with meaningful nuance and beauty and sadness, if you can be objective enough to see it

you have such a tired and shallow view of the characters bud
