Owen, why do you drink with your girlfriend? Does she know about your past or have you just not told her? I know you recently met and started seeing her when you were not drinking and then you had at least one dangerous drinking event since then.
This isn't a game and we are not your mommas. We can't fix this for you and we are not here to absolve you. There is not any reason for an alcoholic to drink - not ever, not one. It's just a matter of time until your life is off the rails again. What has happened in past relationships? Did drinking cause problems?
What about your dad? Does he know you are trying to quit? I told the important people in my life when I was done, because I was D.O.N.E.
I think you need to be honest with everyone in your life, not just an anonymous forum. This isn't the Confessional here. This is picking a side. Don't blow up this woman's life along with yours.
