The answer differs depending on the intent of the question.
For your specific example, "You don't love me, right?" implies that the asker thinks the answerer doesn't love them, and is either seeking confirmation or hoping to be contradicted. Answers might be "No, I do love you", "I don't", or "That's right, I don't love you." Just answering "Right" would be considered very terse, and answering "Yes" would be unusual and ambiguous (see How to answer a negative question without ambiguity?).
For a confirmatory question like "Your house is by the sea, right?", "Right" would be a very normal answer.
