Didn’t Hope break up with Rafe because he wasn’t as good as Bo and she said she would never love him as much as Bo? Pretty devasting to someone’s ego especially when you love them and by their words and actions they are saying they don’t love you. Not surprising he had comfort sex with Sammie when he just lost Hope and not surprising that he did not feel like their love was strong enough to survive the truth.
And Claire is beyond self-centered, but she surely has Julie’s temperment and self-rightousness.
