I think it's more that she was traumatized by the interaction with her rapist... reliving the rape, etc. It didn't help that her husband (who didn't even know that she was raped, but still...) wanted to turn the guy over to the enemy. We haven't seen what she'll be like after seeing the extent of his anger at the rape/ loyalty to her -- just a bit of that with them disposing of the body together, the car sex, and her telling their contact the rapist's death was all her fault and that she had been wrong to question hubby's loyalty. I think at least from here on out, the marriage won't be all one-sided.
