1. "Te quiero, amor mío." This means "I love you, my love." It's a very romantic and affectionate way to express love.
2. "Te quiero." This means "I want you" or "I love you."
The "te" at the end of the sentence is redundant. It's likely a mistake or a creative choice.
So, the meaning is essentially:
* "I love you, my love." (Or)
* "I love you, I want you."
It's important to consider the context when trying to understand the intended meaning.
