Well, that is pretty much what the debate is about.
Is escapism itself the wrong choice to make? In this debate, with the exception of one comment that I recall, it seems like most people have silently agreed that it is the wrong choice without discussing.. Just viewing it as escapism is suppose to make it negative.
So in terms of escapism staying with Lexus is "Finding a backdoor out from your problems to live in a perfect dream world with a woman you felt greatly for but will never have the chance to be with again"
Even in escapism terms that still sounds like the right choice, at least for Rhue at that time.
