Right, it's just that the way some stories and writers emphasize that it's kind of over-the-top you know.
Which reminds me of what to me is the best argument against Parker Luck provided by Dan Slott himself.That's not his nature. At worse, he might ruefully wonder why someone like Johnny Storm gets all the glory while he's public enemy #1. But he would never think of himself as more of a victim than people living through worse situations.
Johnny Storm: I don't believe it. How is it possible?
Peter Parker: Well there was this radioactive spider, and—-
Johnny Storm: Not that. I mean, how can just one guy have it all? To grow up and have someone like your Aunt May there...to be this big hotshot photographer...to have a brain the size of Mr. Fantastic's...and the babes! Man, the girls I've seen you with! God, how I envied you. You always had everything going for you!
Peter Parker: What?!
Johnny Storm: Over the years, I even came up with a term for it. I called it 'the Parker luck'.

I don't know, I feel PI would have meant more if it was presented as something that could have lasted and worked with Spider-Man.But they could have been. Whereas clearly PI, being so removed from classic Spidey scenarios, had an expiration date.
Except in some of those happy memories, Gwen Stacy is not exactly truthful or honest to him...which okay he wasn't that with her either. So maybe he'd accept it in a "I thought I was the one tearing myself lying to her when she felt the same with me". But still, it's not the same.In universe, it's easy to believe that Peter wouldn't dwell on that revelation and instead would focus his memories of Gwen on the happy aspects of their relationship.
Realistically, I think he would. There was that George Clooney movie a few years back, The Descendants. Clooney's character just lost his wife and then after her death, he found out she had an affair with another man and that his daughter knew and he didn't. That movie dealt a lot with the character's difficulty to accept that mix of grief/betrayal/rage and the fact that the entire issue of forgiveness has to be one-sided.It's also easy to believe that Peter would not hold any ill will towards Gwen.
To be honest, I am not someone who cares for Sins' past much as I love the rest of JMS' run (until Sins' Past he didn't write a single bad issue and that's the case for his post-Sins' past work, well except for The Other). I think that story is a disaster and doesn't work...and I am okay with it not being referred to and so on.
