The love story of Lois Lane and Superman is immortal and inevitable. The biggest mistake in the "New 52 Superman", this is something that they are not married. And I hope that this bug will be fixed this year.
Judging from previous comics, Clark is in love with Lois. In the "Superman #14" Clark jealous Lois to her boyfriend.
" No mater how many times he lays eyes on her… he’s always taken aback at the realization that Lois Lane is the most amazing woman he has ever met."
