YOU are definitely worth someone giving YOU their all. YOU deserve that. YOU are entitled to it. It is YOUR right and a completely natural component of YOUR process. It makes sense. There is nothing wrong with it;
Someone else’s “all” is not YOUR “all” though. YOUR values, standards, and expectations are completely different from someone else’s and what YOU may perceive as the minimal given may in fact and truth be their maximum output! Their “above & beyond” could be YOUR “least that could be done”. What is most important to YOU could be of the least concern to them, not out of deference to YOU but because they are just different from YOU. But what is an obstacle in some cases is an opportunity in others. YOU get to decide which is which for YOU. YOU are not wrong for moving on with it (them) or moving on from it (them).
