interesting, what “Larry proof” do you think is Louis being an arsehole / bullying? Genuinely curious- I’m not a Larrie like I said previously so I’m not looking to argue I am genuinely wondering why you think that. Louis doesn’t come across as a bully to me. I just think he has a very jokey bantering ( is that a word) sense of humour.Harry has always been physically close to his friends. the Larry stuff is absolutely insane because it was clearly just teen boys being silly and you can literally view their actions anyway you want to. I personally think Louis is a bully and a lot of the things he said that are "Larry proof" are actually him being an asshole. The fact that Harry significantly distanced himself in like 2013 and has not spoken of Louis since the end of 1D minus saying his name in context of the whole group, twice, it pretty telling.
I do think they fell out like you said, but I still believe something happened between them. And hasn’t Louis said Harry has been to his shows so I don’t think he hates him as much as you think. I just don’t think they talk about each other in public for obvious reasons…
