Apparently, Marvel.com quickly editted themselves. They first posted on the Spidey bio:
"Peter's costumed career has had its share of ups and downs. His first love, Gwen Stacy, died during a battle between Spider- Man and the Green Goblin. Peter has lost other friends, as well - including Harry Osborn, son and successor of Norman Osborn, the original Green Goblin; and police Captain George Stacy, Gwen's father. Peter's marriage to Mary Jane Watson, often troubled by his crimefighting actives, eventually ended. But through all his trials, he has remained steadfast in his determination to use his powers for the benefit of all. "
...but quickly, after folks started shouting on the message boards around the net that he never got divorced, the line was changed to:
" Peter's marriage to Mary Jane Watson often was troubled by his crimefighting actives, and the two have separated."
