Working it out
John and Donna met up after a few weeks of no communication to see if they could fix things between them. John opened up and told her just how her actions affected him and how he felt after finding everything out. She saw his side of the story for the first time and listened.
In return, she told her about her feelings in the marriage and how she felt lonely and without a partner. He saw her point of view and understood why she did what she did, although it was very hard for him to come to terms with it. In the end, Donna moved back into their house.
