How do you say you want him in your life fo rever in spanish?

Te quiero en mi vida para siempre. I want you in my life for ever.

Le quiero en mi vida para siempre. I want him in my life for ever.

Le quieres en tu vida para siempre. You want him in your life for ever.

One problem with this phrasing is that "te quiero" usuallly is translated as "I love you". In my opinion, it may be better to say something like "¿Lo desea en su vida para siempre?"
