Was I rude/extra/over the top?

Basically my boyfriends ex won’t leave him alone, constantly calling/messaging everything. He blocks her number and then she magically has a new number. I told her to leave him alone once, then she messaged me again. I just want to know if the last 3 messages were too rude, or if I did what was right/what y’all would do in that situation.

Oh, and he deleted messenger on his phone but since he still has Facebook he can see her changing his nickname constantly, but doesn’t/cant reply obviously
