Here, wissen is appropriate: you know the fact that the other person loves you.

Why not: "Ich liebe Sie! - Ich weiß!"

[mizinamo]

Why not: "Ich liebe Sie! - Ich weiß!"

Sie is used when speaking formally; you would not normally confess your love to such a person.

That said, your sentence is grammatically correct. You can report it as "my translation should be accepted" if you wish.

[mizinamo]

Would a child say "Ich liebe Sie" to a parent?
