You notice her and she immediately captivates you. Every cell in your body tries to understand just how this human being standing right before you is so beautiful, so perfect. The grace of her movements, her flawless skin, her vast intellect and wit, the clarity of her voice, all seem so unreal. Lust plays a very minor role; your feelings are pretty much pure. Your adrenaline level rises and you feel like you're currently sungazing, she's too amazing to look at directly. But she is so irresistible that you try to ignore that and enter the perpetual cycle of love.
Every moment with her is so blissful that you don't ever want her to recede into the horizon. You want to spend as much time with her without much consideration of your own needs. When she interacts with someone else, your heart flares up in anger, you feel replaced. You yearn to always be at her side and be the yes man to help satiate her craves and endeavor to make yourself seem so much more dependable.
You trust her every word, you kiss the ground at her feet, you praise every aspect of her being; she is an idol, the muse of your everyday thoughts and actions. The house of cards that is your common sense falls over when you are next to her. When she gives you a hug, appreciation, or simply a compliment, you are in momentary bliss; it's as if heaven itself reached down to grace you.
You get cold sweats and endure countless sleepless nights just thinking about her. Staring into her eyes unnerves you. It's as if she peeks into your soul at every instant. You sacrifice so much time in an effort to better understand her. You try to keep your feelings hidden but subtle enough that she could potentially pick up on the hints, given enough time.
But you also feel that she's out of your league, that she'll never understand your love for her. Despite whatever you do, your love feels unrequited; she may only ever see you as a friend. Without her, you lose all purpose. You grow increasingly attached to her and think that maybe she could be the one. You start simulating rejection scenarios inside your telencephalon in milliseconds.
You paradoxically spend time with her, knowing that the more you do, the worse your attachment and the worse the feeling of intense fear of rejection becomes. Intense paranoia sets in, prompting you to express yourself to relieve yourself of the burden weighing your heart down.
At the time of the eventual confession in which you profess your love for her, your heart throbs with fear, and you feel like the fate of the world solely depends on her reply. In most cases, she will say no, leaving behind a gash that simply won't heal. You'll become angry, sad, and erratic, as a flurry of emotions overshadows reason and rationality. Even if the wound never fully heals, you will eventually realize that it was just meant to be and that the real one is just around the corner.
