Joseph,
But (correctly) using that criteria you should also be frustrated and disappointed that your date wasn�t the right person for you even if he/she was a very nice refined Yid.
Two points:
1. There is a much higher potential for a very nice refined Yid to be the right person. A good marriage is based more on a constant, conscious choice to commit oneself to Hashem and his/her spouse than checking off every random box on a list, or some hocus pocus concept of “besheret”.
2. Even if the nice refined Yid was definitely not the right person, despite the frustration and disappointment, there is more hope for the next date than if the previous date was a dud.
