They stood for some time without speaking a word; and she began to imagine that their silence was to last through the two dances, and at first was resolved not to break it; till suddenly fancying that it would be the greater punishment to her partner to oblige him to talk, she made some slight observation on the dance. He replied, and was again silent. After a pause of some minutes, she addressed him a second time with:—"It is your turn to say something now, Mr. Darcy. I talked about the dance, and you ought to make some sort of remark on the size of the room, or the number of couples."

Almost all of Darcy's interactions with Lizzy are just like this. Sorry, I cannot agree at all. He wanted to be near her, yes. He wanted to hear her witty, sparkling banter, yes. But every time he tried to converse with her, he looked, and I believe felt, outclassed. Hey, he was outclassed! I wouldn't call any of his exchanges so far with Lizzy "conversations". Indeed, we've been shown no exchanges at all between Darcy and anyone that could be called conversations, though I wouldn't rule out unrecorded conversations with the Bingley group, and maybe with the officers during their unrecorded meetings.
