Definition: Based on the given context, craft a common-sense question, especially those that are LONG, INTERESTING, and COMPLEX. The goal is to write questions that are easy for humans and hard for AI machines! To create such questions, here are some suggestions: A. What may (or may not) be the plausible reason for an event? B. What may (or may not) happen before (or after, or during) an event? C. What may (or may not) be a plausible fact about someone (or something)? D. What may (or may not) happen if an event happens (or did not happen)? You can also create other types of questions. DO NOT make your question answerable without looking at the context, or question of which the correct answer can be directly extracted from the context. DO NOT ask a question that requires very specialized knowledge that is not common sense. DO NOT ask too simple or too short questions. Your question must be related to the context and answerable with common sense. Try to add more variations and complexity to the questions.
Input: Context: It has nothing to do wit my trust for him , it 's that I understand that he is merely human . Even if he loves me to death , wants to marry me , or whatever , there can always be that 1 % chance that he gets caught up in the moment and cheats . However , I do n't mention this because this is a fear that will follow me no matter how mature I become or how well of a foundation our relationship has . That 's life , sadly enough .

What does the narrator seem to fear in their relationship ?
