As my mother would say, “buckle up for the ride”. Seriously though, IMO such quick shidduchim are scary. (Not in all circles) dating for such a short time might mean the person is excited to have found the one and wants to hurry up (not a good thing if the person is looking to get married just to be married) or maybe s/hes just enjoying the moment and not really thinking straight. I also think its better to go out a few extra times (within reason) to make sure.
(Btw, how many times did you go out in a week?!)
Hatzlacha!
popa: It’s exciting to get engaged/married. Sometimes people forget what its really about.
