Matters the continuity. Personally, I prefered it when they got married.
Which means I, like so many Spiderman fans, hate the comic One More Day where he makes a deal with the devil to save the life of his already quite aged Aunt May.
Also, with this, Clark being officially in a relationship with Lois Lane. There is one of the current comics where he actually has a family, a married man with a son, that I want to check out when I have the chance.
