People don't have to be paired up with anyone. At the moment, we have M'gann/La'gaan with Supey, and Mal/Karen. They're interesting relationships. Pairing up for the sake of pairing up... there's simply not enough exciting story material in it.

I also think your assessment of Nightwing's love life is flawed. He was not with Zatanna. He was with Zatanna, Rocket, and Bette Kane. And probably more.
