Hopefully, Marvel made this self-evident in the comic book ever so many years ago.
*begin geek mode* The whole Pete and MJ thing went on and on for years in the Comic and was infinitely less squished together for obvious reasons. Pete didn't even get to meet MJ till issue 40-something, in a classic Romita "Face it Tiger you just hit the Jackpot" panel. But they still failed to get it together for even longer, Pete going off with Gwen Stacey until her untimely death at the hands of the Goblin (in the scene they pinched for the movie with MJ instead, and she failed to die). After Gwen died, Pete decided that everyone he loved would suffer (the theme that they've yanked out for the movie, which explains why he didn't get it together with her) and it took years before him and MJ finally got it together (I think it was the 80s before that finally happened) and then they got married, and now they've got divorced, lets see what's around the corner for the most interesting comic book couple since Jean Grey and Scott Summers (if she'd just stop failing to be dead all the time).
