This is getting into areas that might be beyond a comic book board, so I'm just going to say when "love" is selfish, it's not love. It's control or jealousy or lack of confidence masquerading as "love."
Even so, it's not a contest. There are no prizes. There is no ranking. There is no title. One can love many people in many different ways, even love the same person but in different ways over time, but that doesn't mean one love is "purer" or "better" or has inherently more value. Each relationship is different because they involve different people and at different stages of their lives. We learn different things from each relationship in different ways.
Agreed.
Also this thread made me read Son of M . Peter still has all the memories in his head of a life that felt like it was real (and wasn’t this a multiverse reality that got merged with 616 thanks to Wanda? Didn’t Slott kill off House of M Peter in Spider-Worse? Or am I misremembering?) but isn’t his. What he seems to actually be upset about is he can’t talk to MJ because he wasn’t married to her in that reality yet he was happy, because he feels she would take it as a betrayal (I don’t think MJ would, she would probably be far more understanding than this writer makes Peter thinks because she knows better than Peter that adult relationships can be messy, but I’m digressing). It’s not that he’s upset he’s not with Gwen, he’s upset because this is putting a wedge between him and MJ.
Later, when Peter mets up with Quicksilver, he doesn’t mention Gwen by name. Instead, he’s angry because he had a son in that reality who he loved deeply and the son was taken from him so now he’s mourning a ghost no one else knew (and probably again feels like he can’t share his grief with MJ although again, she would probably be understanding). His grief is centered on Richie, not Gwen.
