A woman whose husband frequently swears by divorce since their marriage, and he once explicitly told her "You are divorced," but the other oaths are conditional, such as: If your brother enters the house, you are divorced, and he entered, and so on. He argues that he does not intend divorce but considers it an oath. However, she is now trying to avoid any relationship with him and fears that if she distances herself, she will be considered disobedient. What is the ruling on their relationship?
