He would have been 100% believable if he posted this as an anonymous experience but he tried to counsel her on
text.
Try this from a different point of view:
Jonah Hill is not in a secure emotional state and views the world through an anxious nervous system.
Jonah’s anxiety feels relief stating these concerns out loud instead of simply walking away from a situation that is not compatible with his preferences.
Because Jonah feels these behaviors are a threat, he gets triggered to the point where he cannot trust and support a woman who may also be in an insecure state herself.
In a less egregious situation , perhaps he loses his ability to trust her and sabotages the relationship even if she has never stepped out on their relationship. ( - although let’s be honest, this one probably did).
A secure man may have had room for attention seeking behavior and a successful relationship with an insecure woman.
both can be true.
edit: I didn’t realize he was dating a surfer model. I thought the behavior above would be weird but in context I now have to lean into the sabotage a little more here.
