There is certain kind of relationship where you know as clear and pure as Heisenberg's blue crystal meth, that both of you are not working well. Thus, it leaves the best option: to end it. But there is a part of you that so stubborn and dominant, invading your mind saying that you don't want it to end. You still want him; over and over again. Because you thought this would work -- this should have worked as you had put a great deal of effort and feelings. Feelings that you are not easily give away to, that you used to keep in a safe-deposit box behind 1000 feet tall brick of wall but somehow he managed to climb and figured out the secret code or the feeling that you think you may not be able to feel it again. And what's worse is the past keeps playing a magic trick on you; as subconsciously turns everything that you see or hear will remind you of him. But solely reminding about the good things, like your first date at your favourite Japanese restaurant, spontaneous trip to the amusement park, the first kiss. Not the spilled drink over your favourite shoes when you were trying to convey your point in the middle of an intense argument or the unreturned texts that made you worried to death. And all of those interrupt you to make sense of everything.
You are too focused on the fact that you are no longer with him not why you are no longer with him. All you remember is you were once shared good memories together. Your current self is blinded to foresee a long way ahead that moving on is actually possible. Not just some myth or a fairy dust waiting to happen, but a concrete outcome hiding in space and time. You forget that you will meet someone, by chance, not having enough common things to like but enough to start off a conversation which lead to the stage where you are no longer strangers; you will learn to understand the other half of his interest that is apparently completely different than yours or what you thought he would be; he likes to write poems, his favourite movie is a Korean cold-blooded action-thriller film with a lot of killings and bloody scenes and he listens to British Rock from the 60s but regardless, you will still like him. The kind of movie he'd like to see or the kind of music on his Most Played Playlist does not matter. What matter is he makes you feel like more than a diamond ring; he makes you feel wanted and belong. He fills in the void. There, you will realise that it is possible -- to move on. Or maybe, just a tiny bit of a hopeful maybe, you will grow older in a few years time as so does he, and your path will come across with his again, and the older version of you may turn out to be far more compatible with each other. And maybe, this time both of you will get it right.
