As a teacher, I am in no way condoning the relationship in this show. What I do want to comment on is everyone's criticism of how poorly developed Claire's character was. As a woman that has struggled with fertility and had several miscarriages, I can relate to the inner turmoil Claire is experiencing. Her mental state is clearing affected by the stress infertility can have on a woman. It can completely change your personality. Perhaps the series could have delved more into that, but having experienced it myself, I could see how damaged and lost her character was and how she was doing things that she may not have done otherwise. She felt alone, like less of a woman, and abandoned by her husband for his musical "career". It's unfortunate that she turned to the arms of a student in order to feel something, but when I watched her navigate her situation, I could relate to the depression and irrational decision making. I feel like the writer did a good job portraying a woman with immense internal sorrow and struggle, But perhaps failed to portray her in a way that others who haven't been through this experience could relate to.
