My ex texted me again today. It's been over 6 months that I told him that I didn't want to have anything to do with him. He texted twice "just to say hi". I blow him off twice or would ignore his texts. Everything. And today, he texts again. I pretended to be someone else telling him that I changed my number, thinking he'd just leave me alone. He started saying mean and untrue things about me. He probably thought I would snap but I kept pretenting. What is wrong with him? Wouldn't you guys give up if your ex did that to you? What am I doing wrong? I just want him to leave me alone!
