You are recovering as you have said. I think its part of the recovery. Only that your relationship with your girlfriend and other people is at stake. Its good that you are aware of it. Let this awareness help you motivate yourself in the recovery process. Also, like what "reddevil" said, discuss this with your girlfriend so that she'll understand and might be able to help you. I don't know if that really helps but I hope things will get better real soon. Good luck.
