Actually, no, they didn't. As has been said on here what must be thousands of times now, all continuity except the wedding day itself remains intact, with Peter and Mary Jane as a couple but not married. It's really not that difficult to understand, and yet the barrage of misinformation from the anti-BND crowd just keeps up. If you don't like the books and don't want to read them, fine. Obviously that's your perogative. But enough with making stuff up out of thin air. I too own all those issues, as I've been reading since the early '90's, and I still remember and occasionally look back through them fondly. Nothing has been erased except for what I said before.
I found one of the main theme's of that continuity to be the 2 togather after the loss of May after revolations. Aspecially after Norman's return, that has always haunted Peter and is what made him such a top stand out villian because of how personal his battle with Spider-Man was, beyond Gwen's death long ago. But after BND, one of Joe Q's cherry on top was not only undoing their marriage and strong relationship togather but never having mj pregnant since that aged Peter further.
