Answer:
You did not post a question, but I will guess that you want a translation of the conversation.
Carlos is telling Lucia that he is the one in charge, and he is the boss of the house. Therefore, he does not want anyone from Lucia's family to visit them. He even threatens to "break her face" if she does not obey him. Lucia agrees, she just does not want to be hurt.
PD: Kind of an aggressive guy...
