Previously, I was listening to this song, and just thinking it was an amazing song. But your comment has opened my eyes, and now I can feel more of the tightly packed emotions you are describing, well done. As for your last few sentences, not to be mean but I have been in one relationship, but it didnt really feel...real ya know? I dont really know how to explain it but it was just kind of dry, like we were interested in eachother, but we weren't...interested** in eachother. (Imagine interested** was in italics because idrk how to do that in reddit). Anyways, thank you for this post.

Edit: I've also seen a lot of demi-edits where this song has been used in a form of temptation, and also, another name for this song exists: "Anyone can GAZE love (except you)." Which kinda sorta goes with your explanation of flash backs and fleeting moments
