Ash, I see what you're saying, but I connect more with Cha's take on this. I feel like Eli and Oskar saying the words "I love you" isn't necessary and even a bit superficial. Saying "I love you" would, to me, be taking what they express to each other every moment they're together and confining it to the box of those three words. It would feel like a hollow/needless statement to me. I'm not saying their love is hollow, but I kind of feel like those three words are because their connection is so much deeper than "I love you". I couldn't imagine it crossing their minds to say what's so obvious; to take a connection so deep and attempt to place it in a mere "I love you". I feel like those words would downplay/underemphasize their relationship...not take it seriously enough.
Now, this is, of course, one man's opinion. I just feel rather strongly about it

I hope I didn't come off harshly

I do say I love you to my own loved ones, but, to me, it just doesn't feel right here. In fact

I may have just convinced myself to either say it less (I feel like my family throws it around so much it loses its significance) or stop altogether.
I just went on a deep, personal emotional journey. Consider it as if I've been talking to myself this whole time
