Yeah...no. I'm not wrong. I'm actually kinda shocked that someone who is trying to waltz around pretending to be the formative expert on the wall crawler is so off the mark that it's kinda sad and hilarious at the same time.
Gwen was Peter's FIRST love, sure. But not his "TRUE" love. Stan Lee, Gerry Conway (the guy who killed her off and said "Gwen wasn't the right girl for Peter. MJ is. That's why Gwen died--to move Peter towards growing up."), Dan Slott, J. Michael Straczynski have all listed MJ as the penultimate love of Peter's life. And those 4 names combined not only created Spider-Man,Gwen, and MJ, but have written the vast majority of the book ABOUT him. So you're saying that you understand the character more than those that have ACTUALLY written him?
I think what you're trying to say is "because her death weighed so heavily on him that it changed the trajectory of his entire existence" which you would be 100% correct to say; because it did. However, not how you think it did.
Gwen's death was the FIRST death since he got his powers as Spider-Man AND it was indirectly/directly responsible FOR it. Sure, he visits her grave, because it's his way of letting her know, and keeping himself grounded and honest, to his promise to be better and to have responsibility for his powers and actions. She is his greatest failure as a man and superhero. But visiting the grave doesn't imply that the love for her was greater, because if that is the case, then how do you explain him visiting Uncle Ben's grave? He has a "never ending, irreplaceable romantic love for his Uncle, too? Come on, now...
So before you go around and show off your homemade web shooters that fire silly string better than any commercially produced web shooters in the past, and pretend that you are the one stop information block of Spider-Man, let's try to keep the "I knew you weren't a massive fan" gatekeeping nonsense to yourself. Because you are not correct nor do you even have any room to puff your chest out and stand in a superhero pose when it comes to this drivel you just spouted out.
