If it’s the right one then it isn’t the right time.
And I won’t tell you not to talk with your friends. UNLESS you know that they’re going to pull this again. Using single friends as references, especially if you’re looking for different things, is OK, but what’s up with anyone calling the mother to put in a good word for the girl? That would freak me out as a mother. Let them wait till they’re called, if they are at all. Maybe you should mention something to the shadchan about your friend’s overeagerness to help to finess things. Then again, maybe not if it can’t be done in a way that won’t involve any taint of lashon hara.
