My ex is driving me nuts

I transferred to my high school sophomore year and befirended this girl who and we hit it off on the first day. She self disclosed her whole life to a guy she just met (me). I'm now in my senior year and after two years we tried dating. Officially, she asked me out but the feeling at first was mutual. Went well except the fact that she avoided introducing me to her parents and she couldn't find time for a date. I broke up with her because she had some personal issues she didn't want my help with so she pushed me away. We kinda went back to being good friends but I feel that she still is mad at me for something. Also out of the blue one say ahe textex me not to tex or call her until she calls. Since I hadn't texted her for 2 monthes I didn't care. I just have no ide what that random text was.
