I've known this girl for two years. We're both 21 years old. We're in college. She was with her boyfriend for a year. She broke up with him cause he didn't let her breathe. She told me it was a real bad breakup. Months after her breakup, we started to like each other. I asked her out one day but she turned me down. We remained friends. She has avoided me ever since. We text sometimes to each other. She doesn't reply most of the time. I know she's not obligated to text back. I made the mistake of chasing her and I'm tired of it. How do I get her to chase me? Should I stop texting one, two, three or more days? What should I do other than leaving her?
