Didio's comments most recently on marriage were in the context of Batman, but they generally get applied across the board. I think at least with respect to Superman and the much broader acceptance of Lois Lane as his central love interest his position has somewhat softened since New 52. He was reportedly the person that pushed for Jon to be brought over into Rebirth as well as the Supersons. And the success of the Rebirth Superman books should really put the idea that Superman only works when unmarried to rest. It was as successful as N52 was and had much broader critical, fan success along with at least equal financial success.
Bendis for better or worse seems to be on the Superman books for as long as he likes barring a complete sales collapse. And the quick drop in sales that we have seen, or a leveling off more or less, occurred when there was no real presence of the family or marriage. You'd have to be willfully misinterpreting things to come to that conclusion.
I'm a massive fan of Lois Lane and Clark together. So I'm not in favor of any real status quo change. I'm willing to give Bendis the benefit of the doubt right now that he's not going to mess things up between them. I'm just trying to read the tea leaves with all this stuff with Lois in Action Comics and now with Jon being back and being seen in Superman 7. It's hard to see how they get out of this unscathed somehow. Bendis has repeatedly said he has no intention of breaking them up, he might just be giving them an obstacle to overcome together.
