The Torture of self torture

Was watching some video [won't spoil it for you] whereby a person had to purposely make someone he loves stay at home because he wanted to protect her from being killed that very night. He knew the future and thus had to ensure her survival by forcing that decision upon her.

A supporting role then told him, "You know, she'll probably hate you for the rest of her life because of this"... and to which he replied, "I hope so".... it was quite a painful scene watchin him having to deliberately do what he didn't want to do so that in the end, she benefits... and then later on, he had to fake that he didn't know something and so did she and the conversation that went on between the two was heart wrenching coz both are like hurting but yet they can't show it...

It was quite a sad moment while watching the video. That you can or might have to choose to do something you don't want to do and you know that other person wouldn't want to do it too.. but you have to coz in the end, it's the best way or the safest way... to torture yourself so that the other person benefits from it whether knowingly or not. Phew. painful.

could you miss a person so much for so long till you grow numb to missing them? would you forget after a while and would the pain of not seeing them slowly go away?
