Her character took major steps backwards not being Peter's love interest after OMD, to the point she was barely a friend let alone a confidant as they tried different roles for her to justify keeping her in the book on a semi recurring basis.
She remained Peter's wife in other Spider-Man comics around the same time, which always hung over her post-OMD appearances in the book, because it still informed readers of how things ought to be.
Hell, that is still going on even today.
