Traduzione - Portoghese brasiliano-Inglese - more from paulo

Some doubts:
NAO TENHO SEU CONTATO - you translate "I don’t have your contact", but he always calls her "tu" in the rest of the text, as well as in the first message. So, couldn't it be referred to a third person?
TU ESQUEÇESTE DEPREÇA QUE EU SOU CASADO.
I would translate sth like: You were quick to forget that I am married.
NAO TE ESTOU A PERÇEBER COM PAGAMENTOS A MEIO
Couldn'it be sth like "I'm not receiving your half-payments" or "I don't understand what you mean by half-payments"?

Allright. The part of the third person is one particularity of the spoken portuguese on changing "teu" for "seu".
The second one, that's right, fault mine.
But the last sentence is very hard to understand what he realy wants to say.
She typed "I obviously got something wrong"...
Grazie !!!

Do you say "de nada" in Portoguese too?

Didn't get it!!!!

If you didn't get it, you don't say "de nada" as in Spanish. I was asking how to answer in Portoguese to "grazie", how do you usually reply to "obrigado/a"?

Reply in Portuguese "de nada" too.
You didn't specify it was comparating to Spanish, that's why I didn't understand
OK???

OK! Obrigada!

Prego (hehehe)
