You are sweet too
It means, Thank you, you are also charming and beautiful.
Gracias Papá, tú eres muy dulce.
¡TÚ ERES BIEN DULCE! ERES MUY ESPECIAL PARA MÍ Y LO SIGNIFICAS TODO PARA MÍ (standard Spanish) --- You are very sweet! You're very special for me and mean eveything to me
"Tú eres dulce pa' dicerme esto" means "You are sweet for telling me this" however it is misspelled and uses improper phrasing. "Tu eres dulce por decirme esto" is a better, though still awkward way to say this sentence. Pa' is a contraction of the Spanish word "para" which in this context means "for". However the Spanish word "por" (by) can also translate to English as "for" and in this case would be the preferred word.
Tu eres muy lista in English means you're so clever.
Cuan dulce is "How sweet" and Muy dulce is "Very sweet".
