It truly sounds like Elanor has been conditioned to stay with the relationship if she's willing to ignore the first signs of her husband being a sexual predator. Letting her know that you'll be there for her if she does leave him is extremely important in these situations as, like you pointed out, she's probably losing many of her other connections outside the marriage. Leaving a relationship you've been conditioned to think you need can be terrifying and hard, but having a solid rock to hang on to on the other side can be the difference between staying and leaving. I truly wish the best for her and hope she can find her way back to that strong and feisty girl you remember from your childhood.
