even if i stick to the movie alone, there are plenty of examples. but in particular it's written all over his face on their last night together when elio is asleep and oliver looks at him, then back to the camera and looks utterly wrecked. then when they say goodbye at the train station, he gets on the train, the train starts moving and he can't even look at elio because it hurts him so much. because he, OLIVER was heartbroken. because he was losing someone he loved.

when he calls him to tell him about the engagement and says 'i remember everything'. what do you think that was? him trying to get elio to have sex with him again despite the fact that they were no longer on the same continent? no, it was about him expressing his love for him and reassuring elio that he hadn't imagined it.

if you honestly think everyone that loves this film, which includes many famous actors, directors and filmmakers love it because they want to fuck teenagers then you seriously need to get a grip on reality.
