321

n. Used to describe someone who is retarded, moronic, stupid, inept, etc.
Derived from the disorder Trisomy 21, which is the cause for down syndrome. A handy phrase to use in public when you want to call something retarded, but the non-politically correct nature of the word doesn't allow you to do so.
Person 1: "Did you hear that Robbie failed all of his classes?"
Person 2: "Wow, what a fucking 321"
Person 1: "Such a 321... after I told him I failed one, he was like 'That's NOTHING, I failed ALL of mine.'"

321

The antidote to "123". While 123 represents the "noble sacrifice" of letting a soulmate go for their own good, 321 represents the realization that the sacrifice is a mistake. It is the refusal to accept the end, acknowledging that the partner's absence is the true burden, not their presence. It signifies turning back, undoing the departure, and choosing to burn together rather than apart.
Baby, I’m here. I love YOU!
I still love you just as much as I always have. That hasn’t changed. I still feel a deep desire to see you, to have you close, to look into your eyes and tell you face-to-face just how much I love you.
I’m not just in love with you; I’m in love with US. The way we understand each other, the way we laugh without trying, the way we just fit. Being with you feels like home, something I never want to let go of. Every little moment, every glance, touch makes my heart more certain: it’s you.
With you, life feels lighter, love feels deeper, and the future feels like a beautiful promise. You are not my past, you are my "now".
You might think I have options. But really, I’m just refreshing my phone, hoping you’ll text back, because you’re the only person I actually want to talk to.

Let me tell you another secret: I know people who communicate through "last seen" timestamps using our own silent definitions. Well, yours-you are the poet; I became one just for you. And while that makes me so proud of you, it also makes me sad. Why are we such fools to suffocate a love like ours?
You speak of a "movie ending" sacrifice to leave me unburdened, but you are wrong. Your absence is the burden.
I really don't want to let go. Not now, never. You say it's for the best, but nothing is "good" without you since you left. That noble sacrifice we talk about is actually the reason for the tears I shed in secret. Why live in this sadness when we could be sharing life, listening, holding, and facing everything together? I don't want to burn brighter somewhere else. I want to burn beside you.
"Happy" is not the word to describe how I'm feeling right now. And I can see you're not happy either. So why would we sacrifice for each other when neither of us is truly alive without the other?

I refuse to accept that letting go is the answer.
Why are we choosing pain? We could be happy. We could talk, listen, and simply live. Please, don't push me away "for my own good" when my good is you.
I wish you could find the courage to call me. I miss your voice.

"Why are you still visiting that city alone?"
Because I refuse to let go. I go there hoping to find you.

I told you once: "There are two things I never want to lose: one is you, the other is us."
I love YOU!
