Why did Subaru suggest to run away with Rem? In episode 18, Subaru gives up on basically everything and suggests to Rem that they run away to live a happy life in another country. However, he knows that...


   they will all die if he doesn't prevent Emilia's death.


I know that Subaru has suffered a lot at this point and he's broken and hopeless, but surely he would know he would only get three days of happiness AT BEST before he dies again and starts over again. So why did he even think this was an option?
He said that because he was emotionally tired. He was confident that he couldn't do anything more than what he has done so far. At the moment, he didn't want to accept that he was going to die again and again, so he just wanted a little moment of relax with someone who really cares about him, in this case Rem.
