"I can't be a wife. I'm not that sort of person. Wives have to compromise all the time"

This quote by Sarah Brightman speaks with the idea that marital relationship is not for everybody. It implies that marital relationship requires a certain kind of individual, one who is willing to compromise and make sacrifices for the sake of the relationship. Brightman is suggesting that she is not that type of person, and for that reason can not be a partner. This might be interpreted as her acknowledging that she is not cut out for marital relationship, or that she is not ready to make the necessary compromises to make a marital relationship work. It could likewise be analyzed as her acknowledging that she is not prepared for marital relationship, and that she requires to deal with herself prior to she can make such a dedication. Whatever the interpretation, it is clear that Brightman is not all set to handle the role of a spouse.
