Just me is correct
One of the roles of the shadchan is to make sure that both sides know where the other is holding. Why is he not proposing? Is there something concerning him? Is he afraid of commitment? Does he have cold feet?
The shadchan here should lay things out for you, as well as for him. He needs to be instructed that he is dating a girl who is ready to become his wife, but he is also dating a girl who is close to walking away, do to his inaction.
Best of luck, and please keep us posted, often in the CR we never get to hear the conclusions of the stories
