Did Itachi really love Izumi? ... In my opinion, no... What do you think?
[[ I've answered this before.
First of all, if this is your opinion, why ask me? I'm not the be all/end all of relationship questions. I love analysis, but I'm also a person with my own opinions. I'm not Kishimoto.
If you truly believe Itachi did not love Izumi, I cannot and will not change your mind.
My opinion is that people expect Itachi/Izumi to function like most fandom ships where they love is super obvious/obsessive/almost toxic in nature. And this is where they get the idea that he didn't love her at all, because he was never obsessive, or feral.
Not all relationships have to be like that for it to count as love. Just because Itachi and Izumi would've gotten together quietly and raised children in peace (within the context of the genjutsu future he had her see) doesn't mean it isn't real love.
Sasuke would still come first, and that's fine. That doesn't diminish what Itachi and Izumi had. He had no issues with her and wanted to keep her safe, and he clearly saw himself being able to settle and raise children with her. That's a good thing. Considering a lot of the most popular Naruto ships involve one party trying to aggressively kill the other at some point, ItaIzu wins. There's nothing like that here. You don't need all of that drama to have a stable relationship.
ItaIzu is pretty boring and that's a positive note in their ship. He can be in love with her without treating her like another Sasuke.
And again, at the end of the day- people will ship what they want. You don't have to like it or agree with it. It might not make sense to you, but it'll make sense for someone else. ]]
