The ellipsis adds what is known as a `pregnant' or `meaningful' pause, and signifies that you'd like the listener to carefully consider the meaning of the preceding sentence, but does not usually prompt a direct continuation by your opponent.

The pause is correct, but you would have to additionally roll your hands in front of you in the way that in this part of the world is recognized as meaning `go on' or `continue'.
