"i dont know how to capitalize or use punctuation"
If it's said HONESTLY:
"I love you" = "I need you, and I will wait for you. I'm not perfect, but, I'm hoping you love me anyway. maybe, I don't deserve you, but, I'll be so happy if you love me too. I want to have a future with you. I care for you, I want you to be happy, I want YOU, and not just your body. The words don't just cover it, and I will show it to you, every day when you wake up beside me, and believe me, I will always be there when you wake up. Please love me back."
^ I think Oozeworld won.
I love you. It means that there's really only one you, and every part of your wonderful personality makes me feel the butterflies in my stomach all over again. There can be more than one "I love you" coming from your mouth but with everybody you ever love is different.
I agree with StrangeJade. ^
The phrase “I love you” can be replaced with:
You are an EXTREMELY important person to me, and I never want to leave your side. If the rest of the world doesn’t see you as beautiful, it is because they don’t know the meaning of beauty. If they would take a second to look on the inside of people rather than attempt to define a person through a simple glance, they would see that you are very beautiful indeed. I will never leave you if you don’t leave me, and I will protect you with my life.”
