I am going to assume you want to say "I want to marry you". That would be "Quiero casarme contigo".
Yo quiero tu en mi vida porque tu en mi corazon in English means I want you in my life because you in my heart.
I want to see your face and your body.
I want to be your cookie monster.
i want to kis your bubs.....
If the question is: no quiero que te MATE tu novia, then it means "I don't want your girlfriend to kill you". i dont want you to kill your girlfriend...creepy
I want to be your only.
I want to have your child.
Nothing in Spanish..."Yo te quiero." means I love you.
"I want to give you something rich (of good quality)."
I just want to be by your side forever, I love you.
The proper way it is said is: quiero tocar to cuerpo= which means I wanna touch your body
Do you know that I like you ?
