Yeah, your right. I don't like Jess as much anymore, but sometimes she does/says things that make me like her again, and then she'll just do something else which'll make me dislike her again. I think the difference between Adam/Jess's affair and Zoe/Sean's affair was that Adam and Jess did, and still do, love each other, and for Sean his affair was just for fun. Sean proved that when he carried it on after Lucas almost got killed. As for Adam/Alice, Alice & Curtis are better suited.
