This is canon. Not an Elseworlds. Not a dream. As of Justice League #12 Superman and Wonder Woman are together. EW has the story:
Writer Geoff Johns hints that some event — possibly tragic — will impact every member of the Justice League, and cause Superman and Wonder Woman to seek solace in each other and move from super-powered colleagues to power couple. This is no one-issue stunt: “This is the new status quo,” says Johns, adding that the relationship will have a seismic impact on all the heroes and villains in the DC universe.
“The new status quo”. Now you know why they ditched the super marriage.
I have some thoughts on this. But they will come later.
They will not be pleasant.
I’m so upset
