Welcome to this great forum. Come here often.
Since I am a woman with some relationship history behind me, remember that women love men who love them, who are sweet & nice & caring, never threatening or abusive or controlling. As the days/weeks/months go by, if in her heart she knows you love her and you don't pull any crabby crap with her, there is always a chance she will come back to you. Keeping your addiction in check and following a plan for recovery will prove to her that losing her was not worth your DOC (drug of choice).
Good luck!
