I was dating this girl for the past year and during the relationship I admit I got into a drug problem and did some things I maybe shouldn't have done like take her card and spend money on it and not be consistent with her but I really didn't mean it, it was the drugs and not me. My judgement was clouded too because of the drugs but I recently got sober and now I realize what I had.. she really held me down and had her life together (she was a doctor, had a nice car, house, etc) and I don't want to lose that because she really did a lot for me.. I found out recently that she has a new boyfriend which is weird because she left me only a month ago so I feel like she was talking to someone behind my back while we were together. Anyways, how can I prove to her that I love her and win her back? I really miss her and don't want to lose this.
