Not her biggest fan but I think some of the criticism (not here, elsewhere online) about Paige re moving on from Jacques is really unfair.
She was pretty clear before he left that his behaviour had put her off massively and she wasn't impressed by his constant leaps to anger and defensiveness, it's just that he removed himself before she had the chance to actually end it with him. Even as he was leaving when he was telling her he loved her in a roundabout way and wanted her to be his girlfriend, she just said 'it's fine'.
I think she's also got caught up in Adam's higher profile and that's why she's clinging onto him so tight.
