We were born for one another, and there is nothing and nobody in this world that can change that. Because happiness is recognizing yourself in the other, speaking with your eyes, being big enough to say: "I made a mistake, forgive me", forgiving whenever needed. I love you for everything that you represent in my life. You will forever be my Baby and me, your Angel.
"nor nobody" is a double negative, so you need to put "nor anybody". I would change "it" to "that".
To make things simpler, I've copied the text here and the corrections I suggest are in bold type.
