I feel the same. I don't like either of them and don't think either of them should have ever made it through to the show. From what we've been shown I keep thinking something major must have happened on the honeymoon and it seems from what Charlie said last night, yes, it did, she was at fault and has apologised multiple times. Eve clearly won't draw a line under it, won't move forward and has bitched to Polly, who has gone out to bat for her 'friend' who she hardly knows. Now whether she wanted to maul all the fine detail apart, or just get on Charlie's case, we didn't see, because Charlie wouldn't discuss it all with her, not that she has to, but if she had, perhaps Polly and the viewers, may have had a more balanced picture.
Charlie seemed rational enough talking to Caspar, but I was left wondering if she is quick to apologise, but doesn't actually change the behaviour, just keeps repeating it and so the two women are in a circular argument all the time. I have seen more about this on Instagram, not sure if it's been posted here or not, so I won't discuss in case anyone thinks it's a spoiler.
It's extremely unpleasant to watch.
