i think that whatever caused/prompted paul to leave india is the exact moment where everything shifted for the beatles. i am unsure of what exactly happened, but i am certain that paul’s reality collapsed upon him (once again, i dont know exactly why), and it spiraled him into a frantic and awful panic. paul became avoidant, as he often does, and fled, leaving john hurt, as john never thought that paul would become unreadable to him. this discomfort with one another within this all triggered all of their grief, anger, and bottled up pain to fuel an erratic breakup of sorts that somehow always remained loving at the core, no matter how damning it often seemed.
