To be frank there isn’t a good reason, this story should not have been written and they shouldn’t’ have been split up. But there are better reasons, understandable reasons. If the portal device blew up instead or if a building fell on PEter or if she got a fake message where Peter told her he wasn’t coming. She has to have a reason to give up on him beyond just “time”
You continue to try and back away and argue from a general perspective (and engage in ad hominem) because you don’t know the character. “People are different” is not an argument, it’s an attempt to hand wave. Mary JAne isn’t some random person who just showed up. We know who she is because there are literally fifty five years of stories with her in it. We know her hopes and dreams and desires and personality. We can argue what a person SHOULD do, but ultiamately that’s secondary to what Mary Jane WOULD do. And a Mary Jane who was in a relationship with Peter isn’t going to move on. That’s just not in her character. She didn’t move on when she separated from him, crying as she called him, afraid that he had slept with another woman. She tried to move on when he proposed and after OMIT, but found herself back in his orbit in short order. This is a woman who pursues unrealistic goals to be an actress and model. Who stayed with Peter when he was wanted by the government. Who would have bore his child had Norman not killed them. Mary JAne wouldn’t’ have moved on from PEter because she’s loyal to him, that’s true, but she wouldn’t move on from him because Peter is who she wanted. He’s who she’s wanted since she was 17 years old. That’s why she wouldn’t’ make that choice, because it’s not what SHE wants, more than anything.
This is again a ridiculous assertion. She was moving Peter into her apartment when they were transported. They were completely in love and commmitted. The idea that you dont’ think a person could wait a. Few years for someone is absurd.2.she didn't cheat. After years of separation noncommunicatioj and unknowns its silly to imagine any woman would consider that a lock down, let alone Mary Jane flicking Watson.
This is again just a attempt at self-proving without providing any backing3. Your recounting of her past only solidifies that she makes her own choices regardless of what oeter presently wants, and has always done so. You acknowledge those choices from the past, so you should be able to do so now because they are her choices. Just because you dont like the choice she made here doesn't mean she didn't make it.
“The character wouldn’t do that”
“But that did”’
“That’s why it’s bad”.
Mary Jane wouldn’t choose to move on from PEter in that situation any more than she would abandon those kids. That’s what people are mad about. I will not accept that sort of character assassination. Because it does make her a weak heartless cheat. And Mary Jane is not and should not be written as a weak heartless cheat.
TAgain, this is just you saying you’ll accept whatever trash your given. If she goes on a shooting spree in the next issue you can’t complain it’s Out of character because “that’s the choice she made. That’s not an argument.4. You dotn recognize what they want. She told you what she wants and you are choosing not to recognize it. You're trying to box her in to one thing and refusing to accept any other version of reality. Even though this is one that's been presented with her character countless times. Litery. Rami did it, ultimately spidey did it, spectacular spidey kinda sorta hinted at it, ultimate iirc did it, etc. This isnt even anything new for MJ.
