Accidentally followed idek what that means. I'm not forgetting what Leo did, he was horrible and he is a selfish, childish man and he has been from the start. but JJ is wrong too, he never communicated anything, then he broke up expecting Leo to understand what he did wrong then got angry when he didn't. It's fine for them to have broken up after communicating and Leo doesn't change, but that never even happened.
I think the author is saying what you're saying though, I don't think the author is trying to paint JJ as the person in the wrong, just Leo. But what do I know about the authors intentions.
Like, why are you guys forgetting what Leo did to JJ. Why does JJ have to be the one understanding all. Be fr guys, Leo acts childish but is also a grown man.
