Task: Question Answering
Input (English): 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 .
