Ororo Monroe (Storm) & Scott Summers (Cyclops)
Ororo is married to a rather powerful fella most known and feared as T’Challa the Black Panther.
Scott is in a long-term relationship with one Emma Frost, formerly the White Queen of the old villainous Hellfire Club, but has been on the side of the mutant angels for nearly 20 years, and Mr. Summer’s lover for about a decade or so.
There’s a major storyline called X-Men: Schism going on right now that will rip the X-Men’s ranks asunder, pitting them on two very different sides of the Marvel Universe mutant plight.
Looks like after that event there will be some shenanigans, among everything else.
Make of it what you will.
