Let's see, republic5 ... You've got 59 days of sobriety and no girlfriend as a result. Hm, not exactly what you'd hoped for. But you're grateful that you're sober, and that's a good thing. The 12-step program that AA provides as a support system for recovery seems to be something of a natural fit for you.
I'm confused, though, about how this former girlfriend fits into your life. You say, "I am taking a serious look at my life and trying my hardest to change for the better." By which i think you mean this valiant 59-day success at living sober, right?
But then you say, "And on top of that the one person that has stood by (enabled) me through it all has left." the word" in recovery has a negative conotation, meaning helping someone go one using an addictive substance. So I don't know whether this woman who left was important to you in the early stages of your recovery and her leaving hard on you, or whether she enabled you drinking and her absence makes sobriety easier to sustain.
Whichever is the case, you're doing the right things to work your program and find strength through it. I'm so glad you've fouls this forum and hope you "Keep coming back!"
