well i love this girl that i started dating a long time ago. we broke up december of 2003. over the last year she keeps coming into my life and then leaving for months on en. we began dating in early february and then broke up after valentines day. now we agreed to be friends, and she knew that i would eventually hopefully want more. what does she do yesterday? she goes and gets back with this guy she was seeing before we got together atthe beginning of feb. obviously i was hurt and talked to her about it today. she dumped him. what am i supposed to think everyone? do i still continue to persue her as a gf, or as a friend? what do i do? keep in mind she is a bit emotionally unstable, especially over the last year and a half. help me.
