Our psychotherapist says:|
This relationship has done Chloe good. However she looks at it now, the experience will help her build healthier relationships in the future. It seems like she was suffering from classic Peter Pan Syndrome (not wanting to grow up). She was living out a fairytale, while Luke didn't see it that way and wasn't as serious about the relationship.
Luke's unfaithfulness brought Chloe back down to reality and make her realize that relationships don't just work by magic. She's angry with him - understandably - because he hurt her, but she'll realize when she gets into another relationship that this experience has helped her. She was absolutely right to leave him.
