New england girl, it is true that the first thing they tell you when you get out of rehab is that you have to change your playground. So, despite the fact you love the burgers at some pub, you just can not go there anymore. my abf and I have talked about this, his social life is so tied up with drinking, I keep saying there are movies, there are other types of restaurants where you can get just as good food but they are not associated with his drinking or drug use, we did go out this weekend to a new place for that reason. But, mostly, we just spend more time here at my place together, whereas before he would come by, go out to a pub, talk to me on the phone while he ate and drank, and then he would end up disappearing.
It's certainly a journey to deal with an addict. good luck to you
