According to the memoir, Love Warrior, how does Craig respond to the problems in his marriage?

After admitting his infidelity to Melton, Craig vows to win her back and works on himself to make that happen. He shows Melton his support and desire to change by being very helpful with the children and volunteering. When his own therapy teaches him that he has difficulty with conversation, he realizes that is because he has always been afraid of saying the wrong thing. He works on his conversation skills and eventually asks Melton to practice with him. He is patient with Melton as she goes through her own healing process, which eventually leads to the two reuniting.
