hi everyone,
i want to give a collier to the girl i love (and (wich i just found out) loves me too).
Since she is (just like me) hooked to japanese anime & manga, i thought of the idea to add the words: "I love you", but then in japanese...
I tried google translate, and it showed me this:
私はあなたを愛して
fonetical it says:
Watashi wa anata o aishite

(since im hooked to anime&manga i know these words, but dont know if the sentence is right)
I know google translate's translations are crappy, thats why im searching for help.

Does anyone know how to write "I love you" in japanese?

thanks in advance,
dexterd
