And despite those facts, they clearly show that Peter still has a thing for Gwen
during his marriage to MJ... like in Spider-Man: Blue, and the Digger arc during in JMS' run...
And those are just two quick examples...
Mary Jane fans need to realize that Gwen was first at bat when it came to who Peter was going to marry... before the she was tragically killed.
Exactly...
Betty Brant was Peter's "first" love... if you wanna get technical, and Gwen was Peter's true love... as he reached to MJ during the last part of Sins Past, he still utters Gwen's name... you can't put a label on what Gwen meant to Peter Parker.
And also going on technicalities, while they dated from about 1975 to 1978, Mary Jane then disappeared from the books until 1983/84, and they only started to date again just prior to the wedding in 1987... so please don't throw lines like
"her and Peter have been together since the 70's and married in the 80's" because it makes it seem like they were "together" for many many years prior to the marriage, which was NOT the case.
