If you ask me the bulk of Spider-Man readership (aka, most of the people that aren't in this forums) don't give 2 s**t about Peter being married or not, they would read then anyway because what they want is good stories.
Now, i'm a big fan of the marriage and i wouldn't mind if it comes back, but i'm also willing to compromise so i suggest, why not poligamy, you know Peter and MJ has a very deep and emotional romantic relationship, but they still can date other people if they want to, a lot of people do that today and if a superhero should reflect modern society in some level Spidey should be that one, granted it would be kind of OCC for Peter and MJ (Peter in particular is a very old fashioned guy, probably the consequence of being raised by 2 elder citizens with an stable marriage), but at this point i think that Marvel throw consistency out the window a long time ago, besides the main thing that a non comitted Spidey can do is dating other people.
Also i would like if they get rid of the Mephisto deal, that's something that we don't need on Spider-Man story frankly, is just as bad as the "Ben Reilly is the real one" twist in the 90s (and i said this as someone that loves the guy). Keep the Spider-Family away from the main books too please, except for maybe Kaine, those guys are decent characthers for thenselves but i don't want then close to Peter until somebody is able to make an interesting bond beetween then.
Man i ended up rambling again
