Wendy was married with children but left her husband as she realised she was a lesbian. I think this was over 20 years ago, I wasn't watching closely. She was happy with her new female partner and they married with a civil ceremony. Wendy felt that she was in the wrong body and so became a man, Wen. Wen then remarried his lesbian partner and they are now man and wife. Wen's adult children are happy with their dad-mum. I think that was the gist of the story.
