Met a girl. Dont know what to do.

you need her phone #.

 

"Hey, do you wanna go for coffee some time? It'd be nice to talk to someone that's going through the same sort of thing."
The same can be used to get her number Etc. Also, put yourself in the right mindset. Don't be a dick, but remember she singled you out to talk to, not the other way around, so he must want to talk to you. This means that she doesn't find you awkward too much, and you can just relax around her more. If you get all agitated, that's a turn off. Being too chill about everything, turn off. Just be yourself, and think of it like talking to a friend, which she kinda is. Take a deep breath as well, that always helps.

 

 
My gut instinct tells me not to do it. I don't know what your in a drug outpatient program for, but I am assuming it is not for pot. Depending on what you are trying to quit, if she has the same issues you two getting together could equal the biggest mistake ever. When you are trying to walk away from an addiction, you want strong people in your corner, if you attach yourself to someone who is also struggling to stay sober all you are doing is putting an extra weight on you. She is going to want support from you when you are unable to give it and vice versa, and as a result either she or you both will go back to using.
Be friends with her, get her number and have coffee, sure, but wait until you are strong enough to have a relationship otherwise you are going to end up right back where you are right now, but at the beginning. Just about any addiction councillor would probably tell you the exact same thing. Bad idea. 

 

Like I said, take a deep breath Nah, but for real, all my friends who've got into relationships have the problem where they find it hard to date afterwards. Just do what you feel comfortable doing, but push yourself. Often the best looking girls rarely get approached because guys are intimidated by them. The lack of attention makes them think they aren't good looking. When you dive in and assure her he is, in fact, beautiful, good, sexy things tend to happen, at least they do for me

 

If you're shy just play the shy card. Make a dumb reason you need her number for group and start texting her.

 

 
You didn't have to tell me why you are there but I appreciate it, and you are right it can be an extremely dangerous drug. I too grew up in a household that was touched by alcoholism so like you I know first hand just how destructive it can be.  My father also had a very dangerous withdrawal that could of taken his life, he was very close to having to ask one of his family members for a piece of their liver. My brother is actually in the throws of that same addiction right now, but he is not able to come to terms with it yet.  When it starts to destroy your body and affect your relationships and work, you know its a problem. Only you really know whether or not alcohol is affecting you that way.
Even if you don't have a problem and you are just there paying lip service, I would still hold off on dating anybody from there. If anything, she could have a real problem and not be able to handle a relationship yet, and next thing you know you are on her wild ride of drama and self destruction. That is a really painful place to be when your in a relationship. 
Just stay focused on you, do the best thing for you, make choices that will better your life. Once you are where you want to be, then you can worry about bringing other people into your world.  When you find the person that just makes your world complete, you want to be able to give them the best you possible.
 
Good for you man
