Fraction's Worldwide Man Hunt did a lot of work with Pepper but that comic also had Tony cheating on Pepper with Maria Hill...or Tony cheated on Maria with Tony but didn't tell either of them.
If you saw the movies, then RDJ's Tony is the guy who tries to change and prove he has a heart after that and does make efforts to change, which is reflected in his relationships with his supporting cast. In the comics, fundamentally Iron Man is more or less the same guy before and after the cave with box of scraps. So readers are wondering what's the point.
And ultimately the real issue is that MCU Iron Man offers a complete story. If you see Robert Downey Jr.'s Tony then he has a beginning-middle-end. That's pretty rare for an actor who introduces a superhero to the public. Chris Reeve didn't offer a complete story of Superman in his movies, nor did Michael Keaton's Batman, or Tobey's Spider-Man. Christian Bale's Batman did yes but since he wasn't a foundational actor it was seen as one interpretation among many. With RDJ's Iron Man you have that. So after getting the no-filter best version of Tony, you go to the comics and see perpetual f--k-up dude who goes from girl to girl, then it will be hard for audiences to sustain interest.
That falls into a lot of sexist cliche patterns, i.e. the casanova who always gets his heart broken and so on.
