It might be “too much of a good thing” literally. You have been bombarded with him and not have had a chance to get to know him and become enamored with him. Seriously, 6 dates in one week does not allow the psyche to absorb it all nor get used to this other being and become attracted to him. How can one know in one week whether you are attracted to him. Its like discovering a new ice cream flavoring and gorging yourself on it till you are full of it. You know its good and you like it, but your not sure why you were crazy over it when it first came out.
I agree that you should keep going and you will find things to be attracted to. It might not be the whole package, it might turn out to be his amazing smile, or his charm and charisma, or the way he looks at you that really grabs you and throws chills up and down your spine. It may be the way he shows cheesed others that makes him the most beautiful person you know and that’s what attracts you. It is something different for everyone. Look around you and try to figure out how other shidduchim come to be. Sometimes people look so mismatched and one would be hard pressed to figure what one would have seen in the other.
Give yourself a chance to get to know him and you might surprise yourself and see how attracted you might really be to him. If it doesn’t click for you however, then don’t let anyone push you into a relationship that doesn’t work for you. Hatzlocha.
