I might be remembering it wrong, but did you happen to revise some parts of the story? I remember their child was still a baby, and there was a scene where Wena and Dylan's child fell into the pool because Dylan left to see the child she had with her mistress because she's sick. Or am I mixing it up with a different story? I'm sorry, I'm not completely sure if this is the same one. I just remember reading a story before where Rhian's character also had a mistress.
