Who in his right mind would take what Jaye said so seriously to the point of abandoning his home and his loving parents for years?
And at the same time he leaves his sister with the thought of her being the reason why her parents can't see their son
His moronic choice is also the main reason they can't mend things and all the unsaid is left to fester for years
No wonder she's full of anger
Just my two cents
The mc has already decided to leave before that last big fight, the fight was just the reason he left that night and not a few weeks later.
His moronic choice and no wonder she is full of anger ?
The mc loved her, while Jaye was being apathetic and spiteful for ten years, with the only reason that he made one mistake as he was 8y old and all he wanted was her to have more friends (and Jaye know this).
I can assume being in love with her was extremely painful for the mc, hence the decission to leave, to move on from Jaye and the unhealty relationship they had.
Also what do u expect ?
Jaye behaves like she does for ten years and apparently didn't give a damn about his feelings and when the mc finaly couldn't take it anymore and decided to move on from her, he should just come back because now she is ready to talk...after she finally sees what her behavior caused.
That being said him leaving in the middle of the night was a shitty move towards his parents, not Jaye thaught. She had ten years to talk, the mc tried to talk with her and to understand her (he says that in the bar scene).
Also what is Jayes reaction in that last fight ?
She sreams at him, says she never wanted a brother and that he should leave, followed by her trying to punch him in the face.
And while Tara goes after the mc, she showers, thinks that she is happy with what he did, that it was just what she needed him to do and rubs one out, she didn't even think one time how her action would affect him, no guilty conscience at all....how exactly should we call her behavior ?
