The short answer is NO.

You were ignoring her and she got you to bite on the bait she threw out there. What she did was a planned and calculated effort to get you back into her life. For some people even bad/hurtful attention is better than none at all.

You got tricked into contacting her, next time no matter what she says of does do not bite. She will go away sooner or later but the more you engage with her (even through legal channels) the longer she will hang around.

What I would do is make sure I had the business card of any and all police officers that are aware of the situation just in case something else happens.

For now the best option is not to escalate the situation but if it continues then an order of protection can be requested through the court.

Be smart and don't let her drag you into her dysfunction.
