This one’s tricky. I wouldn’t be mad at her, but if she replaced me, why should I take her back? I wouldn’t want her to throw the other guy away either, but if we actually took time to discuss what was happening and work through the respective emotions, I wouldn’t be willing to live with her again if that’s what she wanted. My number one priority would be getting back in the lives on my kids though.
Tom Hanks plays guy that gets stranded on an island after a plane crash. He survives for a few years, makes a raft, leaves the island, gets found, goes home, his fiancee moved on after he was declared dead. She has mixed emotions, missed him (kissed him), but also loved her new husband and family. Ultimately they decide not to get back together, like you said.
