It should be "ich danke Dir für all das Gute und Liebe und Schöne", which literally translates to "I thank you for all the good and nice and pretty (things)", a very intensive way of saying "thank you for the good times" when seeing someone you spend a lot of time with for the last time.

You are really nice = Du bist wirklich nett ( "du" is used as subject)I love you = Ich liebe dich ( "dich" is a direct object)I gave you this = Ich gab dir dies ( " dir" is an indirect object)hope this helps ;-)
