What does tu mi amor mean in spanish?

You are my love. nope it means you my love.

but i dont know if this person was answering something like a quien quieres mas = who do you like most? and they answered with Tu, mi amor = you, my love

or if they wanted to say you are my love.

if you meant my first answer then your right if you meant my second answer then it should be "tu eres mi amor"
