Can you write her a letter and not send it? I did this multiple times with my friend/almost girlfriend who recently quit compulsively contacting. I used the notes app on my cell phone. I analyzed the situation to death until I finally had some semblance of closure. This kept me from actually contacting her compulsively. I also talked about the situation with other people who I trusted when I got too obsessed with her. It has been over a month since I last contacted her. I still miss her and think about her a lot but I am not obsessed with contacting her anymore. In fact, I am looking for other women to date.
