Seven Reasons why DCnU Superman will be single. 
Number 5: Flashpoint Lois Lane
                     Lois Lane has gotten new attention in 
 "Flashpoint," being given her own series, "Lois Lane and the Resistance."  
In the three-issue story, Lois Lane is single. She's never met Superman, and she never reported about his existence.  
"Lois is exactly the character we know and love, except just  remove from her equation the fact that she's ever met Superman," said  Dan Abnett, co-writer of the "Flashpoint" tie-in series with his  collaborator, Andy Lanning. "She's the spunky, snarky reporter she  always was, who hasn't necessarily had the breaks she's had in the DC  [Universe], because she never got that star scoop story of Superman."  
The story centers on Lois as a reporter who becomes stuck in the  middle of a war zone, and she eventually gets caught up in the local  resistance movement.  
The end of the main "Flashpoint" series, which will be released  on Aug. 31, is supposed to be the precursor for the big changes DC is  making in September. But it's the tie-in story of single reporter Lois  Lane that opens the door for the character to be single even longer.
