Hi Jet and welcome to SR
you will find friendship and support here if you need it .
I dont know what the answer to your problem with your girlfriend is , but if her reason to leave had anything to do with the booze, it might be time to take a look at stopping, cos as you said , it wont make it any better .
Stick around and have a read of the sticky posts , and I am sure that people will be along to welcome you shortly
