A guy walked out on his girlfriend and I want her to suffer the consequences

I told my friend that I'm moving back to my hometown and he introduced me to his cousin who's a girl. We had been seeing each other for about 3 months and it was all going pretty good, until she told me that she wanted to be more than just casual dating and I told her I wasn't ready for that. She said she was disappointed but I didn't give a shit because I wasn't ready. She told me I'm not a man if I didn't love her and that she deserved better than a man who doesn't know what love is.<br><br>I told her I didn't love her and that she was too needy for me to love her. She said she was going to call her friends and get them to scare the shit out of me. She told me I should be scared and that I'm not as tough as I think I am and that I should be afraid because I don't deserve to be loved and that I'm just a worthless piece of shit who deserves to be punished.<br><br>I told her I didn't love her and that she was too needy for me to love her and I walked out. I haven't talked to her since and she's been sending me texts and trying to call me but I've been ignoring her. She's been saying some pretty nasty shit in her texts and I want her to pay for the shit she said to me but I'm not sure how to make her suffer.<br><br>Is there anything I can do to make her suffer? I don't want to go to the police and I don't want to do anything illegal. I just want her to pay for what she said to me.
