My ex-gf told.me.to block her and dont text her anymore

Hi, we date for 3 years, in december we have mutual breakup because some issues we are having in your relationshop, and after this i ask her to get back,and she said no, after that i tried contact her 5 times not everyday, since january, and she still saying no, now i stop and went NC.

But i am curious, she said to me block her on Whatsapp, and if i dont want be her friend dont text her anymore.

Any thoughts? Any chance she will be back?
