He could still make her want him
Maggie would never have made the journey to Northumberland to see her ex-husband if it hadn't been for their rebellious teenage daughter. Lindsey had formed a disastrous relationship and Neil was the only person who could help.
Clearly, Maggie's treacherous betrayal some years ago still rankled with Neil because why else would he so provoke and humiliate her? She was ashamed of the fact that he could still make her want him while seemingly remaining detached himself. Surely he must be involved enough to want to help Lindseyeven if he suspected she might be another man's child?
