Continue to ignore her or tell her to stop contacting me?

My previous question that I had asked everyone to provide an opinion on was supporting my concept to continue ignoring my ex girlfriend.a short run down for you is this.my girl and I broke up about 4 months ago, basically because she wanted to be with someone else and currently is with the same person. During this time we continued to talk but for the past month I have completely ignored her texts and phone calls! I took the advice I had gotten from everyone on here to continue to ignore her. AFter taking the advice to continue to ignore her, she had begun to text me more constantly for the past 3 days. Not with anything mean, but with hi, or how are you.still no response from me. Yesterday her final text was "I really wish you would just stop ignoring me." My question is if she's so in love with her boyfriend, why wouldn't she just stop contacting me after I haven't responded for a month? Also, should I text her back next time she writes me something with "will you please stop contacting me?" or something of that sort, or should I just continue to ignore her? It's eventually gotta stop at some point doesn't it? Or not? I really do not want to be mean to her because I really did love her but enough is enough.please help me :(

Do you think she is trying to just keep me around for a :just in case" things don't work out with the guy type of deal, or do you think she actually truly has feelings for me still?
