What is the nature of nurse relationship with juilet in romeo and juilet?

The nurse raised Juliet so they have something similar to a mother daughter relationship. They are considered "close friends". The nurse is always kind and loving to Juliet. She tries to give Juliet the best advice she can. However she cannot step too out of bounds because she is still a servant (especially when her mother or father are around- they treat her with less respect than Juliet).

Hope this answers your question :)
