Isn't she enduring this for her son? I don't think she's "folding" she probably just wants to be pregnant fast so she can see her son again or I'm wrong idk.
This IS a time regression. The things in the future haven't happened yet. There's no reason for her to not "fold"
It still happened to her tho. You'd think the PTSD would make her feel grimey at his touch.......she thought he killed the mother of his child for petty reasons, after cheating on her in her face no less. If he seems like someone capable of that, is that not a reason to "not fold?" She never shared a single good moment with him as adults, but he still got her gushing and blushing. Her obsession with him actually needs to be explained more, cuz he's been almost nothing but a curse, a source of stress and opression.
It happened to her yes, but she's also smart enough to know that the past events haven't happened yet. And she also still has to have her baby.
And considering we don't know the full truth, just what she saw. Makes her an unreliable narrator. Did he Actually cheat on her? Bc she never confirmed it. It wasn't like a god saved her and said "this is what happened".
She saw one thing and made a jump in conclusions.
And again, those events haven't happened yet. She's smart enough to know about the butterfly effect
What you know and what you feel are two different things. If she folds now, the only context is "he hurts me, but I still like him *doki*doki". You said she's rational, but that doesn't seem rational. Love isn't a good enough reason, she loved him and tried her best last time, but look what happened. And given his thoughts in this timeline, he's only thinking like a trashy abusive tsundere idiot. So, even if we don't hold him for other timeline offenses, he's still toxic and cruel. I only mention his alternate self offenses as it would affect a human being (the MC) that experienced it. I hadn't even begun to clock his actual tea lol
Oops, forgot to say. He thinks like an abuser. And most of them also say "but I was hurt as a child" "I don't know how to love" "I do it for you, for US" "You betrayed me first when you-" deadass. He also uses a lot of abuser tactics, like tearing her down when he doesn't get a reaction he wants, extremes between hot and cold. Urges to isolate, jealousy, delicate masculinity, thinks his treatment is okay because at the end of the day he doesn't let "others" do it though.
why she folded so quickly....
