How do you say "I love you" in Dari (Afghan Farsi)?

I keep looking online but I’m not sure if it’s Iran Farsi or what. Also, there’s so many different spellings like dostet daram, dooset daram, doset daram, I don’t know which is the correct one!

Also, anyone know of any good CD’s and books to learn this language? :) My bf is learning and I think it’d be cool to know how to speak a different language together.
