Yes she certainly do own am apology to Darren , but not to Zhou Zinchen It all happened because Zhou Zichen was coward and weak , he was silent when his family was metally abusing her and after she left he is saying he is not angry and crying. His silence only encouraged his family to do whatever they wanted , and in process ruining many lives including his and his children.
As a third party, it's hard to judge who is right or wrong between a couple. I think my main issue is Florence leaving her son behind. I understand if she needed sometime because the end of the relationship and whatever trauma experienced was still fresh in her mind. Based on the information provided so far, 30 years is a long time to not make any attempt of contact, even if it is checking up on how Darren is doing with her family.
