Newsflash: Love goes in cycles. There will be times when you don't love your partner and aren't attracted to them. Good marriages remember that--regardless of love and sex--they are friends. You don't treat your friend like crap. You care about them, and you work through it. (Or you don't, and you let each other go.)
Morrison played this for stupid boringly drawn out character assassination drama and to boost his pet, Emma. When Claremont broke Scott/Jean up, it actually read like an extension of previous continuity. And HEY! He remembered that the most important thing about Scott/Jean is that they. are. FRIENDS.
Not that it matters anymore. I quit X-men years ago, then picked it up because of Morrison's promises. He didn't carry through, his execution was dull and wordy to the point of putting me to sleep. I quit after the "Jean makes Scott fall in love with Emma!" plot and only follow it here, in vague hope that someone will stop fucking up the 616 franchise.
