Max Crighton doesn't love anyone but himself. He doesn't love his wife, nor his two children, Leo and Emma. He's told his wife, Maddy, several times that the only reason that he married her was because of her money and the connections her family gave him as a lawyer. That all changes in a trip to Jamacia to look for his uncle David. While there, Max is brutally attacked and 'sees the light' where his wife and children are concerned. He even sees everything that is wrong with his relationship with his parents.
Maddy Crighton has her love for her children to sustain her. When Max leaves to Jamacia, she realizes that she never loved the person that Max truly was, just the illusion of him. When he comes back 'different' Maddy is unsure of whether to trust this extrodinary change that she sees in Max. It's true that he seems to really love his children, but Maddy isn't sure that she can risk her heart again, no matter how much he is changed.
