mail message to my girlfriend from someone else... do i need to be worried?

On the first sentence, there's no gendre for the subject, so it could be "he bit his tongue" or "she bit her tongue". That's a common expression in Spanish for saying that someone is so bad that he/she could get poisoned with his/her own words.

The "I love you too..." I think it's on an ironical way, so I don't think you have to worry! :)

The last two sentences are not very clear, because "responds" is not Spanish, it's more French, and it means "you reply" or "reply" (imperative form). It could also be a mistake that would be "respondes", and it also means "you reply". The "you don't want to say: WITCH" I think is like that person is calling "WITCH" to your girlrfriend...
