"Let's Leave Things Here For Now..."

I've rarely had to use that line. In fact, of the many guys i've dated (i don't know an actual number, i find it negative to start dating and keep track of the number of guys you've been out with from the beginning) I can only remember one where I had to put the evening out of its misery by using it.
The first time, I can't remember who the shadchan was, but it was so not shayach, we just sat in silence in the hotel lobby most of the time. This was when silences were still awkward for me. now, if i have nothing to say or want the guy to contribute a bit to the conversation, i'll "allow for" or "arrange" silences until he says something. In this case, it was a sentence here, a sentence there but for the most part silence in between sips of soda.
I finally decided to end the awkward evening by saying "let's leave it here for now, and we'll be in touch on the phone."
More recently, a friend suggested someone for me. My father wanted to meet him first, maybe screen him, and the boy insisted I not be there when they meet. (it happened to be i was going out anyway, otherwise I would have...resisted, let's say)
when we actually met in the hotel lobby, some kind of mental wall clanged down in my head (like prison doors slamming shut) and I had nothing to say to the guy by way of conversation. we sat down and ordered drinks and straight off the bat he started asking me the kind of questions you ask when you have nothing else to say: "so what kind of music do you listen to?" (i wasn't going to tell him I don't like most jewish music) "what do you like to do in your free time?" the funny thing was, the shadchan in this case had advised me not to talk about current events, future plans, or "my animals", but the guy brought up every single one of those topics!
There were some silences, and the thoughts racing through my head were what kind of excuses i could give for getting out of this date. it was going nowhere, and it was almost physically painful to just sit there avoiding/not avoiding each other's direct look.
I couldn't tell him I was meeting friends and had to go because we had prearranged the time for the date. I couldn't tell him I needed to get home to my mother because...what for? Every so often (I counted 4 times) he would ask me "so is there anything you want to ask me?" but there wasn't. I had asked him everything i could think of, his family, his education, future plans.
I told myself i would do the polite thing and stick it out for one hour. but after 40 minutes of painful awkwardness and the fourth "so is there anything you want to ask me?" i decided to put an end to the date and used the only polite thing left to say. (i seriously wracked my brain for anything, something nice to say to end it) I told him we should leave it here for now and be in touch over the phone. he seemed agreeable to this and as soon as he had walked me to the door of the hotel, he bolted. Yes, bolted.
the funny thing was, the next day the shadchan called to tell me he wanted to go out again.
